Hello.
When a java class use a fpc library that call jni.CallVoidMethod inside a
thread it crash the application.
If the fpc library call jni.CallVoidMethod directly (not via a thread) =>
perfect, it works.
Is that a known problem ?
Maybe does it exist something else than jni.CallVoidMethod for inside a
thread (like synchronize or queue for procedure of object) ?
Here the java error message :

Did you use AttachCurrentThread and DetachCurrentThread?
Pay attention to the validity of local references as well as their number.
Posting some code might help.
