    JDK Version Problem with RHDS + JBoss 4.2.2 + jdk 5 update 1

    mr.pyisoe Nov 20, 2007 9:37 AM

      I have updated my jdk 5 update 12 to 14.

      I tried to deploy a .jar(which contains some entity beans and sessions beans) to both and the following exception occured.

      When I changed the exec environment to jre 6 update 3, it worked. And it also worked on jdk 5 update 12. The problem is only with jdk 5 update 14.

      What is the problem???

          The "Bad version number in .class file" is the error message you get when you try running a class compiled with the 1.6 compiler with a 1.5 JVM. Either recompile with 1.5, or run with 1.6.

          Complaint: the error message used to give the class version numbers so that you at least had a clue what went wrong. Someone must have complained that the class version number (48 for 1.4 and 49 for 1.5, I think) didn't match the release number so Sun did the easy thing - dropped the number from the error message. Boo.
