simple approach; Split 'grow' into 'growEmpty' and 'growFull'
- java.lang.reflect.Array can instantiate an array w/ a given array-type and length
- array-type is Class<? extends T[]>
- We either deduct the array-type via array.getClass(), or pass it (ctor for empty Ringbuffer).
- Split 'growBuffer(T[] newElements, int amount, ..)' into:
- 'growEmptyBuffer(T[] newElements)'
- 'growFullBuffer(int amount)'
Allowing a more clean API w/ simpler semantics.

SyncedRingbuffer and lock-free LFRingbuffer.
SyncedRingbuffer is moved from JOGL to GlueGen, and generalized w/ common interface Ringbuffer
to allow testing diff. implementations.
- Added Ringbuffer.AllocEmptyArray factory interface, allowing to pass a constructor
to construct the generic array.
- Added functionality is growBuffer(..), allowing to either grow a full or empty buffer,
using Ringbuffer.AllocEmptyArray.
- Removed explicit 'clearRef' at get*(..), always clear the taken reference for better
interface generalization.
- Added LFRingbuffer, exposing lock-free get*(..) and put*(..) methods
using the 'Always Keep One Slot Open' pattern using the read/write index as barriers only.
- Ctor's copy an optional passed user array into the internal array,
utilizing Ringbuffer.AllocEmptyArray.
- Added unit tests.

access (2)
- Completes 23341a2df2d2ea36784a16fa1db8bc7385351a12
- Replace 'DynamicLinker' interface w/ well documented one
- All DynamicLinker methods are now considered secure, i.e.:
- open/lookup and close utilize reference counting on handle via a hash map.
- lookupSymbol(..) and close(..) impl. validate the passed library handle
whether it's retrieved via open*.
This is the fast path, not that expensive.
- lookupSymbolGlobal(..) performs
Check acccess of 'new RuntimePermission("loadLibrary.*")' if SecurityManager is installed.
This is the slow path.
- DynamicLibraryBundleInfo now reflects the security requirements,
i.e. whether priviledged access is needed.

compatible w/ file scheme.
Regression of (Bug 683, Commit b98825eb7cfb61aead4a7dff57471cd2d2c26823).
The URI encoded path cannot be read by File I/O (if file scheme), since the latter
requests an UTF8/16 name, not an URI encoded name (i.e. %20 for space).
The encoded URL is produced if calling 'uri.toURL()' and hence
the new 'IOUtil.toURL(URI)' provides a custom conversion recovering the UTF name via 'new File(uri).getPath()'.
Tested w/
- synthetic URI/URL coposition (unit test)
- manual w/ moving 'build' to 'build öä lala' for gluegen, joal and jogl.

'gluegen' C Structs on-the-fly (2-pass actually).
Convenient annotation processing (APT) hooked to 'javac' (1.6) via gluegen.jar META-INF
service provider 'javax.annotation.processing.Processor' -> 'com.jogamp.gluegen.structgen.CStructAnnotationProcessor'.
Am implicit APT / JAVAC would be possible, however - to have a proper process
the unit test utilizes an explicit 2 pass run:
<!-- Annotation Processor Only - First -->
<javac destdir="${build_t.java}">
<classpath refid="junit.compile.classpath"/>
<compilerarg value="-proc:only"/>
<compilerarg value="-J-Djogamp.gluegen.structgen.debug"/>
<compilerarg value="-J-Djogamp.gluegen.structgen.output=${build_t.gen}/classes"/>
<src path="${test.base.dir}/com/jogamp/gluegen/test/junit/structgen"/>
</javac>
<!-- Javac Only - Second -->
<javac destdir="${build_t.java}">
<classpath refid="junit.compile.classpath"/>
<compilerarg value="-proc:none"/>
<src path="${test.base.dir}"/>
<src path="${build_t.gen}" />
</javac>
Original code from Michael Bien's 'superglue' git://github.com/mbien/superglue.git,
finally merged to GlueGen (as once intended).
Note: The APT javac pass requires to use 'gluegen.jar' instead of 'gluegen-rt.jar' !
The 2-pass process also alows using the runtime gluegen-rt.jar and hence ensures
clean namespace check at compilation.

and privileged access)
This review focuses on how we perform permission checks,
or better - do we circumvent some assuming full privileges ?
Some native methods do need extra permission validation, i.e. loading native libraries.
Further more AccessController.doPrivileged(..) shall not cover generic code
exposing a critical feature to the user.
Further more .. we should rely on the SecuritManager, i.e. AccessControlContext's
'checkPermission(Permission)' code to comply w/ fine grained permission access.
It is also possible to have full permission w/o having any certificates (-> policy file).
+++
We remove implicit AccessController.doPrivileged(..) from within our trusted code
for generic methods, like Property access, temp. files.
+++
SecurityUtil:
- Remove 'getCommonAccessControlContext(Class<?> clz)',
which returned a local AccessControlContext for later restriction
if the passed class contains all certificates as the 'trusted' GlueGen class has.
- Simply expose convenient permission check methods relying on
SecurityManager / AccessControlContext.
PropertyAccess:
- 'protected static void addTrustedPrefix(..)' requires AllPermissions if SecurityManager is installed.
- Remove implicit doPrivileged(..) triggered by passed AccessControlContext instance,
only leave it for trusted prefixes.
IOUtil:
- Remove all doPrivileged(..) - Elevation shall be performed by caller.
DynamicLinker:
- 'public long openLibraryLocal(..)' and 'public long openLibraryGlobal(..)'
may throw SecurityException, if a SecurityManager is installed and the dyn. link permission
is not granted in the calling code.
Implemented in their respective Unix, OSX and Windows manifestation.
Caller has to elevate privileges via 'doPrivileged(..) {}' !

Tests:
- Property access
- File access
- Native library loading

test array offset working correct.
The 'carray' pointer returned from GetPrimitiveArrayCritical(..) is moved about the array offset
and used in ReleasePrimitiveArrayCritical(..) to release the pinpointed memory.
Even though this 'is' a bug by violating the _sparse_ specification, Hotspot impl. doesn't use the value at all (NOP)
and hence this code didn't produce an error since .. (Same w/ Dalvik).
A followup commit will fix this issue.

binding initialization
- OSX/Java7 w/o 32bit tests
OSX/Java7 has no 32bit JVM, disable d32 tests for such, using property 'use.macosx32'
- Reliable Test1p*JavaEmitter JNI binding initialization
Load libs and init JNI binding statically w/ @BeforeClass,
since OSX/Java7 for some reason gets confused (?) w/ init sequence.
This is no issue for JOGL etc .. as far we have observed.

Added the ability for users to set a "resolver" in JarUtil
that lets it find resources that are loaded by a custom classloader.
This is needed in OSGi apps (like Eclipse RCP apps), since OSGi
resources do not have simple jar: URLs (they use a custom
protocol called bundleresource:).

'\D.*' matches a leading non-digit and then any character.
First the string is tokenized by delim:
"OpenGL ES GLSL ES 1.0.16" -> "OpenGL ES GLSL ES 1", "0", "16"
Enhance pattern as follows and access collected group if matching:
// group1: \D* == leading non digits, optional
// group2: \d* == digits
// group3: .* == any pending chars, optional
final java.util.regex.Pattern nonDigitsCutOff = java.util.regex.Pattern.compile("(\\D*)(\\d*)(.*)");
Reorganized storage from atomic values to int[3] array, allowing simple pattern matching loop.
Added unit test.

JNILibLoaderBase.addNativeJarLibs(..): Add API doc
JNILibLoaderBase:
"addNativeJarLibs(Class<?> classFromJavaJar, String allNativeJarBaseName, String[] atomicNativeJarBaseNames)" ->
"addNativeJarLibs(Class<?>[] classesFromJavaJars, String singleJarMarker, String[] stripBasenameSuffixes)"
Derive the 'all' (1st choice) native JAR URL solely on the given class's JAR URL.
Examples:
JOCL:
// only: jocl.jar -> jocl-natives-'os.and.arch'.jar
addNativeJarLibs(new Class<?>[] { JOCLJNILibLoader.class }, null, null );
JOGL:
final ClassLoader cl = GLProfile.class.getClassLoader();
// either: [jogl-all.jar, jogl-all-noawt.jar, jogl-all-mobile.jar] -> jogl-all-natives-<os.and.arch>.jar
// or: nativewindow-core.jar -> nativewindow-natives-<os.and.arch>.jar,
// jogl-core.jar -> jogl-natives-<os.and.arch>.jar,
// (newt-core.jar -> newt-natives-<os.and.arch>.jar)? (if available)
final String newtFactoryClassName = "com.jogamp.newt.NewtFactory";
final Class<?>[] classesFromJavaJars = new Class<?>[] { NWJNILibLoader.class, GLProfile.class, null };
if( ReflectionUtil.isClassAvailable(newtFactoryClassName, cl) ) {
classesFromJavaJars[2] = ReflectionUtil.getClass(newtFactoryClassName, false, cl);
}
JNILibLoaderBase.addNativeJarLibs(classesFromJavaJars, "-all", new String[] { "-noawt", "-mobile", "-core" } );
Efficiency / Performance:
- Reduced JAR URL lookup calls JarUtil.getJarURL(..) - JNILibLoaderBase, Platform, JarUtil
- Attempt loading Jar files (native, class, ..) only once - TempJarCache
Code Cleanup (IOUtil, JarUtil, :
- IOException if not found
- IllegalArgumentException if null argument

'android-armv7hf' and 'linux-armv7hf' ]
- Platform gets new ABIType [ GENERIC, ARMEL, ARMHF ]
- Platform impl. needs to guess ABIType in case of ARM,
since no Java system property ('os.arch' ..) reflects the new EABI.
I consider this a bug, since this will also hinder JNLP to work.
The latter also uses 'os.arch' sys property to determine the nativelib resource!
(See Platform.guessABITypeImpl(..) for details how we guess the type.)

Android ClassLoaderUtil cleanup;
- Add 'asset' URLConnection
- Please read API doc 'PiggybackURLConnection' and 'AssetURLConnection'
- Solves generic resource handling where platform locations may differ,
ie ClassLoader lookup on Android in the 'assets/' subfolder.
- New Android 'AssetDexClassLoader' uses 'assets/' folder for findResource(..)
- aapt.signed (our APK ant task)
- uses 'assets/' folder
- adds the 'assetsdir' attribute allowing to copy other assets into the APK
- IOUtil uses URLConnection / incr. effeciency
- using URLConnection on all getResource(..) since URL
is connected anyways for validation and URLConnection can be used by caller right away
- String getRelativeOf(URL, String) -> URL getRelativeOf(URL, String)
- preserves scheme, authority, etc
- simple parentOf handling, more efficient
- reusing new 'asset' protocol impl.
- Android ClassLoaderUtil cleanup;
- Use createClassLoader(..) impl for build-in static jogamp and user APKs,
which removes code redundancy
Tests: New code path, especially 'assets' are covered by new unit tests, no regressions on Linux.

'spawn off' process to become the lock owner.
To avoid complicated synchronization via synchronized, wait and notify between one thread
and a 'spawn' off thread which temporarly requires the hold lock,
RecursiveThreadGroupLock allows to add and remove other threads to become owners of the lock
as if they were the original holder.
This simplifies some rare locking use cases, eg. in JOGL's GLProfile initialization sequence
where a SharedResourceRunner thread is taking over initialization of shared resources.
