Entitlements do a stack walk to find the calling class. When method refences are used in a lambda, the frame ends up hidden in the stack walk. In the case of using a method reference with AccessController.doPrivileged, the call looks like it is the jdk itself, so the call is trivially allowed. This commit adds hidden frames to the stack walk so that the lambda frame created for the method reference is included. Several internal packages are then necessary to filter out of the stack.
