Look at NATIVE_STATIC_METHOD and NATIVE_NONSTATIC_METHOD.

All the code to unwind the stack is in _svmf_interpreter.  Though the
exception object is built by the native method or one of the
method/function it calls.

GC is usually trigger by creating new instance and not enough memory.
There is also a native method that forces gc.
Java_java_lang_Runtime_gc.  There is a single gc entry point that will
stop all threads (except the current one) before doing the actual gc.
Look in gc_copying.c.
