[jeff.yuchang]

Hi All,

While working on this issue (https://jira.jboss.org/jira/browse/SOA-708), I got the following exceptions when I press 'Ctrl + C' to shutdown the AS.

Detailed information from dump thread as following:

Can someone please shed me some light on this? What cause would it be?

Thanks
