windows native code memory leak?

I’m doing some offscreen rendering using JOGL under Windows and may be running into a memory leak. I am using a 2/17/04 beta release of JOGL 1.0. I’m hesitant to upgrade, because it took me a long time to get everything working, but I will if I have to.

My code renders a 256x256 image and returns it as a bitmap. I’m not using PBuffers. Apparently, after about 600 calls, the server shows 750MB of memory in use. Only 15MB are used by the Java VM. I assume the rest must have been allocated and not released by the JOGL DLLs. Is this possible?

Does anyone have any suggestions on where I can go to start looking for this type of leak or how to possibly avoid it.

Regards,
Daniel
