Description
The following code implements frame::frame_size in src/cpu/x86/vm/frame_x86.cpp:
int frame::frame_size() const {
RegisterMap map(JavaThread::current(), false);
frame sender = this->sender(&map);
return sender.sp() - sp();
}
It builds the RegisterMap from the current thread. This should only works for the top
frame. This will cause an assertion failure in JavaThread::current() in that the current
thread is not a java thread.
