java.lang.NullPointerException at org.glassfish.hk

Question

I get this error/warning each time I do a deploy of the application. I use netbeans 7.2.1 IDE, Glassfish server 3.1.2 and primefaces 3.3.1. The deploy is successful but I'm curious about the reason why this appears.

I think your issue is the same as this known bug - Glassfish 18513. I was actually looking this up the other day.

From what I can tell it doesn't cause any issues, but it is unsettling. It does have 26 votes so hopefully it's fixed soon.
