result in an error
The root cause of this error was the fact that
WindowsPbufferGLContext.destroyImpl() uses WGL extensions to clean up
resources associated with the pbuffer. Because these extensions are in
the public WGL interface, they are wrapped by the DebugGL. However, an
OpenGL context is not current at the time these routines are called,
and it is illegal to call glGetError() at those points. The DebugGL
pipeline was implicitly calling glGetError() after each of those
calls, leading to the failure.
This bug unmasked a couple of others. The code in the DebugGL needed a
recursion count to make sure that glGetError() didn't get called in an
infinite loop. Also, as a side effect of the fix for Issue 160,
calling getGL() on the GLJPanel outside of GLEventListener.init() was
causing a NullPointerException to be thrown. The GLJPanel has been
fixed to return null in this case, and the specification of
GLDrawable.getGL() has been improved. In order to make the behavior
between the GLCanvas and GLJPanel similar, the GL object is now reset
in the GLDrawable each time the underlying OpenGL context is
recreated. This allows end users to set up e.g. the DebugGL
unconditionally in their GLEventListener.init() method. The JOGL demos
have been changed to reflect this.
The test case in the bug report will be updated with code similar to
the originally submitted test case (i.e., the Animator is started
early) but which now works.

Added addNotify and removeNotify to GLJPanel which clean up the
associated OpenGL contexts and other resources. Extended JRefract demo
to stress GLJPanel creation and destruction. New code appears to be
correct. Can see resource leaks when the bunny is loaded over and
over, but believe these are probably due to allocation of large NIO
buffers that are not getting finalized promptly. Stressing the Gears
demo with both the pbuffer and software rendering paths shows that the
OpenGL resources are being reclaimed properly.

old rendering model.
Added SingleThreadedWorkaround.disableWorkaround(); for now, don't
want to add this to the core JOGL API because at some point the
SingleThreadedWorkaround should hopefully really become an
implementation detail that no application should have to worry about.

The test case specifies alpha bits in the GLCapabilities, which caused
the GLJPanel to create a TYPE_INT_ARGB BufferedImage to store the
results of the readback of the frame buffer for rendering into the
GLJPanel. This appears to not be the correct thing to do, because it
causes this BufferedImage to be alpha-blended with whatever other
rendering is performed into Java2D's backing store. Therefore when the
button was redrawn, its image would show up in this backing store
alpha-blended with the OpenGL rendering results since both were
redrawn simultaneously. I believe the correct solution is to never
create a BufferedImage with an alpha component for the framebuffer
readback even if alpha bits are specified in the GLCapabilities. This
is what has been implemented in the JOGL source base.

Fixed Issue 124: SIGSEGV on Fedora Core 3 / NVIDIA
Stability problems have been reported on all three of JOGL's major
supported platforms (Windows, Linux and Mac OS X) whose root cause is
multithreading-related bugs in vendors' OpenGL drivers.
On Windows, the most recent version of NVidia's drivers (66.93) when
run on a GeForce 6800 causes a blue screen of death upon exit from the
simplest JOGL demo (Gears).
On Linux, JVM crashes have been reported upon exit of certain test
cases on NVidia hardware. The same test case causes a report of an
unexpected async reply from Xlib on ATI hardware (at the last time of
testing -- I no longer have access to a Linux machine with ATI
hardware because all of their currently available drivers crash the X
server on my machine).
On Mac OS X, low-level warnings from Cocoa are printed in
multithreaded JOGL situations which can lead to JVM crashes.
All of these problems' root cause is that the current OpenGL drivers
on the market, or supporting software built on them, were not designed
to be used in a multithreaded fashion. Most C programs which use
OpenGL are either single-threaded or perform all of their OpenGL work
from a single thread. JOGL was originally designed to support OpenGL
rendering from arbitrary threads and appropriate synchronization was
introduced into the library to handle this. However, we have had to
scale back this support as stability issues have been encountered.
The most recent round of reported bugs, including the PC crash upon
exit of the JOGL demos, is serious enough that we must take drastic
measures. Support was introduced in earlier JOGL releases to move all
of the OpenGL work performed by JOGL and users' code via the
GLEventListener on to the AWT event dispatch thread. It turns out that
doing this works around all of the above reported bugs. In JOGL 1.1
b08 and 1.1 b09, code changes were made to make this single-threaded
support more correct; this checkin includes another small set of such
changes, including some to the GLPbuffer implementation, and changes
the default of the flag controlling this support to true.
-Djogl.1thread=true is now the default. -Djogl.1thread=auto restores
the behavior of previous releases, which was to enable the
single-threaded mode only with ATI cards. This auto-detection
mechanism was not robust enough and adding cases for the crashes above
was not feasible. -Djogl.1thread=false disables the single-threaded
workaround. Older synonyms for this system property,
JOGL_SINGLE_THREADED_WORKAROUND and ATI_WORKAROUND, remain in the
source base for the time being. Changing the value of any of these
system properties is not recommended.
The expected performance impact of these changes is minimal. In
earlier JOGL releases it appeared that the overhead of making a
context current and releasing it each frame was very significant and a
key differentiator in being able to match C performance. More recent
tests seem to indicate that this is no longer the case, at least with
current hardware. Regardless, we must achieve stability in order for
the library to be useful and this seems to be the best means of
achieving that goal.
We believe that the compatibility impact of these changes for existing
JOGL applications will also be minimal. For correctly-written JOGL
applications, the only visible change in behavior should be that the
values of thread-local variables accessed through the
java.lang.ThreadLocal class may change since the actual thread on
which the GLEventListener's callbacks will be executed may have
changed. Multithreaded JOGL applications performing complex
inter-thread synchronization may see subtle differences in behavior.
We hope that such applications and the developers writing them will be
able to handle this change in behavior without much trouble.
We will continue to work with graphics card vendors to improve the
stability of their OpenGL drivers. Until that happens, we believe this
change will yield the best possible improvement in stability and
portability for applications using JOGL.

This was a bug in the SGI GLU sample implementation and was reproduced
by converting the attached test program to C and compiling in the code
from the sample implementation. This bug was already fixed in the Mesa
sources as bug 2510 and the patch was found at
http://cvs.freedesktop.org/mesa/Mesa/src/glu/sgi/libutil/mipmap.c?rev=1.6&view=log
by Googling for the terms "mipmap.c last row". The fix is to add a
test-and-clamp for the highest row read from the texture.
There is still a problem with visual artifacts when scaling
non-power-of-two textures that this test case reproduces and that is
continuing to be investigated.

Fixed / worked around problem found by user mustang on the javagaming

the Java signatures of the affected methods to take Buffer again

Fixed Issue 61: Make debug variables load from system properties
Added a hardware acceleration path for GLJPanel implemented using the
GLPbuffer interfaces. If instantiation of the pbuffer fails, the
GLJPanel implementation attempts to catch the resulting exception and
fall back on the existing software rendering path.
The new code has been successfully tested on Windows. This checkin
attempts to make the needed changes to the pbuffer implementation on
other platforms, but the GLJPanel continues to use software rendering
until all platforms can be tested.
Additionally, references to static final DEBUG flags have been made
settable via system properties. "jogl.verbose" enables certain
printing statements. "jogl.debug" enables all debugging printing.
"jogl.debug.GLContext" enables the debug printing inside the GLContext
class. The system property names are chosen by convention and are not
enforced.

set pixel format"
This is probably due to JOGL trying to request a double-buffered pixel
format for the offscreen surface. To prevent applications from having
to explicitly set the DoubleBuffered property of the GLCapabilities to
false, the GLCanvas now clones the incoming GLCapabilities and
disables double-buffering before requesting the underlying GLContext.

(ATI-specific)
The root cause of this bug was not the new DummyGL code, but severe
bugs in ATI's OpenGL drivers where it appears that if an OpenGL
context is ever made current on more than one thread during the
lifetime of an application, problems begin to occur such as the
SetPixelFormat call failing on the just the next newly-created HDC, or
all subsequent SetPixelFormat calls failing on all
subsequently-created HDCs. This was occurring because the
single-threaded ATI workaround's automatic detection mechanism was not
being enabled until the first time a context was made current, but by
then it was typically too late; the context was made current on the
end user's thread during e.g. Frame.show(), and if it was ever made
current on another thread (like the AWT event queue thread, which is
where all OpenGL operations are performed when the single-threaded
workaround is enabled) then the problems would begin.
The failure has only been seen on Windows so far; ATI's drivers on X11
seem to be better behaved. The workaround is to check for the presence
of ATI's drivers very early during JOGL's initialization, by looking
in the system directory for atioglxx.dll, and enabling the
single-threaded workaround if it was found. This workaround causes the
attached test case to work properly.
Also added some more debugging code to make diagnosing problems like
these easier in the future.
