JNI在AppKit线程上不起作用

Question

I'm calling a native function from my Swing application on Mac. The call comes from AWT-EventQueue-0 thread. I call some async native API and end up in a callback in the AppKit Thread ( [NSThread isMainThread] == TRUE ). The problem is JNI doesn't work on AppKit thread. For example, call to env->FindClass cases a SIGABRT that crashes my app. However, JNI works correctly in the EventQueue thread.

How can I execute native callback code inside AWT-EventQueue-0 thread or make JNI work inside AppKit Thread ?

Not sure if this will help as it's hard to know exactly what's going on without more information, but I've run into this problem when I store an env pointer in one thread, and then use that pointer in another. The different threads need their own env pointers.
