- Multithreading / Locking ..
It turns out that there exist platforms with a
buggy thread safe OpenGL/GLX/.. implementation.
E.g. Linux x86_64, NV 185.18.14 where 1/6 attempts
of the test case
java -Djava.awt.headless=true demos.es2.RedSquare -GL2 -GL2 -GL2 -GL2
will result in:
C [libGL.so.1+0x5c08a] glXGetFBConfigAttrib+0x40a
[error occurred during error reporting (printing native stack), id 0xb]
Java frames: (J=compiled Java code, j=interpreted, Vv=VM code)
j com.sun.opengl.impl.x11.glx.GLX.glXGetFBConfigAttrib1(JJILjava/lang/Object;I)I+0
j com.sun.opengl.impl.x11.glx.GLX.glXGetFBConfigAttrib(JJI[II)I+67
j com.sun.opengl.impl.x11.glx.X11GLXGraphicsConfiguration.glXGetFBConfig(JJI[II)I+24
In these cases, you can set the system property
nativewindow.locking=true
to always use the generic reentrance capable
LockingNativeWindowFactory implementation as a last resort.

once; don't remember the JVM static initialization rules which
probably define why it was getting called twice

The current thread default display or
the given display is being used,
hence it is no more required to use a ToolkitLock
for X11 without AWT.
Removed X11 ToolkitLock in case of X11 without AWT,
which is being detected with the absence of the classes
java.awt.Component _AND_ javax.media.nativewindow.awt.AWTGraphicsDevice
or with the system property
java.awt.headless=true
Only in the Java2D/Swing case, one 'leaking' Display
is created within canCreateGLPbuffer().
- Workaround for Hotsport bugs #4395095, #6852404
4395095 JNI access to java.nio DirectBuffer constructor/accessor
6852404 Race condition in JNI Direct Buffer access and creation routines
- Added build.xml
-Dbuild.noarchives=true property to skip the time consuming
creation of zip archives.

It turns out that under some circumstances,
e.g. >3 threads within initialization time,
the static X11Display usage result in a
native deadlock within glXQueryServerString().
The call never returned. May be
This happend even with NativeWindowFactory.getDefaultFactory().getToolkitLock().lock();
Removed X11Util.getStaticDefaultDisplay()
This allows us to remove the ToolkitLock around
these segments, due to a thread local X11Display utilization.

- Add: NEWT pumpMessages/dispatchMessages
- Handled by the Display implementation for all windows
- Windows .. OK
- MacOSX .. OK
- X11 .. OK
- Added Atom Property handling to attach java window object to window
- Removed the eventMask for dispatching messages,
since dispatching is for all windows now.
(Wasn't impl. for all platforms anyways)
- All init static code will funnel in the Display.initSingletion(),
to ensure a proper init order for all platforms.
- Display creation is unique for (name,thread).
Handling a TLS mapping of display-names to Displays.
- GLWindow: autoSwapBufferMode and eventHandlerMode are static members
- Tested with experimental tagged
GLWindow.setRunPumpMessages()/runCurrentThreadPumpMessage(),
1 thread - 4 windows, etc ..
java demos.es2.RedSquare -1thread -onepump -GL2 -GL2 -GL2 -GL2
No benefit ..
However .. the implementation is more correct now,
due to the display/current-thread message pumping.
- Fix: Window.sendMouseEvent() bounds check
- Fix: MacWindow has proper nsView locking now,
local to the window instance. locked in lockSurface
besides general window manipulation.
- Fix: JAWT utilized JAWTUtil.init() to
init libraries - NativeLibLoaderBase.loadNativeWindow("awt")
call was missing. (Visible on MacOSX + AWT)
- Fix: GLXUtil proper locking
- Fix: X11Util proper locking
