The following program fails to record the call to LinkedList.offer from readDataFromOpenFile. The output shows that readDataFromOpenFile is called and the probe that directly monitors LinkedList.offer when called from readDataFromOpenFile does fire and the jstackStr shows that it is called directly from readDataFromOpenFile. The probe with Kind.CALL is missed. Hopefully this is a horrible error on my part, but I don't see it.
