In the byteman docs, Section "Stack Management Operations"/"Checking the Call Tree", the example given at the start of the section is incorrect.

It uses: callerEquals("myOtherClass.handleIncoming") This should be either callerEquals("handleIncoming") or callerEquals("myOtherClass.handleIncoming", true)

As is, the example will never run since it's passing a class name, but the default behavior is to only compare to the method name.
