Subject [jira] Commented: (GERONIMO-2168) NPE when deploying RAR
Date Mon, 10 Jul 2006 20:50:30 GMT
    [ http://issues.apache.org/jira/browse/GERONIMO-2168?page=comments#action_12420169 ] 

Tim Howe commented on GERONIMO-2168:
------------------------------------

I made the following change as well:

{{
            if (instance instanceof GBeanLifecycle) {
                checkIfShouldFail();
                try {
                    ((GBeanLifecycle) instance).doStart();
                } catch (Exception e) {
+                    System.err.println("e = " + e);
+                    e.printStackTrace();
                    stateReason = "the doStart method threw an exception. \n" + printException(e);
                    throw e;
                }
            }
}}

And on stderr out comes:

{{
e = null
}}

Then the e.printStackTrace() generates an NPE of course.  According to the Java spec this
behavior shouldn't even be possible.  Does anyone have any thoughts?
