\nThe second extract compiles with an error XygotMessageService1.java:[19,8] illegal start of expression<\/code>.
\nThere is an extra comma in the activationConfig initialiser list in the MessageDriven annotation.
\nThis simple error causes several hours of search, frustration and a waste of time, because
\nit was buried in a large Maven project. Obviously, the MDB were part of
\nEJB package Maven module inside a multi-module Maven project.\n<\/p>\n\nI cannot get those hours back, not ever.
