Try to provide valid instance of HotSpotResolvedJavaMethodImpl to CompilerToVM::getResolvedJavaMethod with offset set to 0. It'll lead to a crash:

assert(((Metadata*)obj)->is_valid()) failed: obj is valid

an test example to reproduce problem and hs_err are attached


Also, probably related issue is that externally setting Method** raw pointer to HotSpotResolvedJavaMethodImpl and providing it to getResolvedJavaMethod(uncomment line 85-93 in attached source to enable this logic) will make it return null value.
