Re: Surface Already Locked Errors?



This has not been resolved. I have seen the error in both full-screen and not-full-screen configurations.

I think it might not have anything to do with the way I built my application, because:

1) This exact application does not have these problems in Windows, Solaris, or OS X 10.4 (as far as I know)
2) The problem comes and goes.


It seems as though my system just gets into a "Surface already locked" mood, and starts giving these errors consistently. And then mercury goes out of retrograde or something and the problem disappears.

I have not filed any official bug reports because:

A) I'm running Beta 5 of JOGL/JSR231, not the latest nightly build, so I can't be sure they haven't fixed this already;
B) It seems quite unlikely that this bug is Apple's fault -- much more likely a JOGL bug;
C) It might not be a JOGL or Apple bug at all, but rather some defect in my application.


All I was looking to the list to find out is what the #$%^&* this error really means. I remember getting a similar error a decade ago writing DirectX apps on the PC, but for this error to be like the one I used to get there, it would have to be very deep in the GLCanvas implementation.

Using the current (Beta 5) build of JOGL/JSR231, I'm getting the errors
occasionally under 10.3.9:


apple.awt.EventQueueExceptionHandler Caught Throwable :
javax.media.opengl.GLException: Surface already locked   ........

I'm interested if this got resolved or not as JSR231 Beta 5 on 10.3.9 is one setup what I'm writing will run under. I haven't seen this myself but you will have exercised it much more than me, and my use may be slightly different to yours (running full-screen, manually invoking the display method, AWT only, etc.)
