An unexpected exception error

john.preston · May 6, 2004, 10:05am

Hi, I have “An unexpected exception has been detected in native code outside the VM” error whenever I try to run two different GLCanvases in tow different JFrames. When I open the first one it works. When I try to make the second visible I get the following error:

An unexpected exception has been detected in native code outside the VM.

…

I don’t know how to proceed. I have tried to restrict the calls to the canvas if it is not visible but this does not seem to help. Can anybody point me in the right direction to a solution.

Thanks

Could you please file an issue on the JOGL web page (Issue tracker, left hand side of the page)? Could you include the specific OS version, graphics card vendor, and JDK version and vendor being used, as well as a test case? Thanks.

Ok. But one question. I went to the issue tracker page but I don’t see where to file an issue. The help stuff only deals with searching the database and voting on an issue.

I’ve tracked down the error to the destroying of the context. Is there some special stuff to destroying the context.

My OS is Linux Fedora Core-1 2.4.x kernel, with XFree 4.3 and ATI 9800 Pro card, driver 3.7.6. The output of glxinfo is:

Does anybody know what is the correct code to ceate a canvas, then add it to a JPanel for display, then remove it from the JPanel and then add it back again. Whne I try to add it back again, I get the exception. I’ve tried all the jogl binaries and the exception remains.

I’m trying to get a main panel to display the GLCanvas and then when the user selects something, the main panel displays another pane, then when the user switches back, the GLCanvas gets redisplayed.

But once I remove the GLCanvas from the main panel I can’t add it back with the exception occuring.

Any thoughts anbody.

I think this is clearly a bug and you should cook up a simple test scenario for this and submit it to the issue tracker.

Just an FYI: I’ve successfully had 3 GLCanvases displaying simultaneously (each using it’s own FPSAnimator). 1 is in a JWindow, the other are in JFrames. The canvases are never “removed” from their containers, but the containers are opened/closed which starts and stops the animator on demand.

Just thought you might like to hear a positive in the negatives.

Thanks. I’m gonna try to put together a bsic senario that dies and post it for others to try.

Ok. I’ve got the error happening everytime. Can anybody check
and see if it does this with thier setup. Compile the following code.
Run it with ‘java -Djava.library.path=/usr/lib:. -cp .:jogl.jar JInternalFrames’
and when you have the internal frames and the GLcanmvas one,
minimize the GLCanvas one, then double click on the minimized
title bar which should restore the GLCanvas frame and the
system crashes.
