Willem Jiang commented on CAMEL-1529:
-------------------------------------
Since spring provides OSGi bundle after Spring 2.5.5, and JmsConfiguration
uses PackageHelper to check if the Spring version upper than 2.5.1.
I'd like to add check of Null Point in PackageHelper to walk around this
issue.
> PackageHelper.isValidVersion NPE in osgi
