I was doing some research related to AccessController, and I noted
this code [1] in StackFrameInfo#getByteCodeIndex():
@Override
public int getByteCodeIndex() {
// bci not available for native methods
if (isNativeMethod())
return -1;
return bci;
}
Now bci is of type short, and given the spec of the method, should the
return not be:
return bci & 0xffff;
instead? Else it would return wrong values for methods with more than
32767 bytecodes in them.
