Good Day, I am getting the java.lang.reflect.UndeclaredThrowableException at $Proxy1.getMBeanInfo(Unknown Source) from the MEJB in JBoss 4.0.4 GA when the MBean throws an IOException. According to the code the XMBean throws an MBeanException in this case but somewhere along the line it is converted to an UndeclaredThrowableException. This causes a problem because UndeclaredThrowableException is a runtime exception.
