    deployment of EJB using Java 7 try-with-resources fails

    Guenther Bodlak Newbie

      I have problems deploying the following stateless ejb to jboss 7.0.2.

      The cause of the problem is the new java 7 try-with-resources statement in combination with a variable declared ouside of the try block.

      The following code does not make sense its just a sample to reproduce the problem.


      Is it a good idea to run AS7 with Java 7 or would you suggest using Java 6?

          deployment failes with:

              System.out.println("result=" + result);
