JDK1.5 causes Swing+JNI doesn't work sometimes

The background is:

- GUI is built with Swing

- JNI mechanism is used

- In native code, there are some memory operations.

(Each compoment is unit tested and proved to be working fine)

The situation is:

(1) When compile and run with JDK1.4, the application always works fine.

(2) When compile and run with JDK1.5, the application doesn't work sometimes. UI crashes with "segmentation fault" occasionaly.

I did a lot of debugs, but failed to isolate the component which causes the problem. I guess it's most likely caused by potential impacts from JDK1.5.(JDK1.5 is a big release with many changes)

Anyone got similar experience/problem while upgrading from 1.4 to 1.5?

Anyone has any ideas, tips or implicatons?

Thanks in advance!
