Ok I have solved my problem of GLException by using the flags earlier.

In JAWT_JNI.c, I see that Java_com_jogamp_nativewindow_impl_jawt_JAWT_GetDrawingSurface0__Ljava_nio_ByteBuffer_2Ljava_lang_Object_2 creates a new NIO buffer each time whereas it is totally useless. A JAWT_DrawingSurface instance should contain a single NIO buffer as a class member and reuses it instead of creating a new direct buffer at each call.
