[jira] Resolved: (VELOCITY-786) NullPointerException while
evaluating template
[ https://issues.apache.org/jira/browse/VELOCITY-786?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pawel Urban resolved VELOCITY-786.
----------------------------------
Resolution: Fixed
Fix Version/s: 1.6.4
The problem had very simple cause - Log.
I temporarily fixed the problem by
Velocity.setProperty("runtime.log"logsystem.class", "org.apache.velocity.runtime.log.NullLogSystem");
just before init.
