    4.0.4.CR2: NullPointerException when EJB3 returns a value mo

    Andrew Steeley Newbie

      Since I upgraded to 4.0.4.CR2, I'm having a problem calling a stateless EJB3 from inside a Quartz job via simple JNDI lookup code:

      public final void execute(final JobExecutionContext ctx) {

      InitialContext jndiCtx = new InitialContext();
      RemoteEJB3Interface ejb3 = (RemoteEJB3Interface) jndiCtx
      .lookup("the remote JNDI binding");

      String somedata = ejb3.method();
      }


      The lookup works correctly, and most method calls work correctly.
      But when I call a method that would return an unusually long string (specifically, more than 10240 characters) I get the following exception:


      java.lang.NullPointerException

      BUT if I use the local interface in lieu of the remote, everything is peachy. I realize that I should be using a local interface here and this post isn't really a question, just an observation. I assume this is an undocumented feature since 10240 seems to be a bit of a magic, undocumented number as far as I know. In any case, I didn't have this problem in 4.0.4RC1
