                 URL: http://jira.jboss.com/jira/browse/JBESB-391

            Reporter: Kurt Stam
         Assigned To: Mark Little
             Fix For: 4.0


When running the deployToSar task of the hello world quickstart on a running jboss, the timestamp on the jbossesb.xml changes and the parameters are reloaded. When this happens sometimes see the following stacktrace:


15:18:25,687 INFO  [Server] JBoss (MX MicroKernel) [4.0.5.GA (build: CVSTag=Branch_4_0 date=200610162339)] Started in 40s:875ms

15:19:12,515 ERROR [STDERR] Exception in thread "Thread-15" 

which is thrown from the line 160 in the XmlValidatorImpl:

parser = builderFactory.newDocumentBuilder();

The issue seems to fix it self, as it seems to be successful 5 seconds later.
