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

      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?

       

       

      @Stateless
public class VerifyErrorBean {
    /*
    deployment failes with:

    Caused by: java.lang.VerifyError: Inconsistent stackmap frames at branch target 129 in method inet.module.is.dao.VerifyErrorBean.doIt()V at offset 52

    */
    public void doIt() {
        int result; // without the variable it works ...
        try (OutputStream out1 = new ByteArrayOutputStream();
             OutputStream out2 = new ByteArrayOutputStream();) {
            result = 1;
        } catch (IOException e) {
            throw new RuntimeException("Some Error", e);
        }
        System.out.println("result=" + result);
    }
}

       

      Thanks
