Hi, Under JBossVsJavaJDKVersionMatrix, there is a statement:- "JBoss AS 3.2.6+ and 4.0.1+ are the ONLY versions to be fully functional under JDK 5, due to JMX issues" Question is:- 1) What are the JMX issues tat cause (JBoss AS 3.2.5 or earlier) to be not fully functional on JDK 5? 2) If an application(on JBoss AS 3.2.5 or earlier) compiles & run under JDK5 is it still ok?
