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.
