[jira] Updated: (VELOCITY-728) NullPointerException occurs when
#parse() without parameter
[ https://issues.apache.org/jira/browse/VELOCITY-728?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jarkko Viinamäki updated VELOCITY-728:
--------------------------------------
Attachment: velocity-728.patch
This should fix it.
If #parse doesn't get an argument, a VelocityException is thrown with information where the problem occurs.
The previous code didn't obviously work and instead of throwing exceptions it just wrote things to Velocity log. This same problem is related to other directives as well (no checking whether we actually got the argument or not and no exception in case of error).
