bug in velocity 1.5 parser

[Josh Singer <jo...@gmail.com>]

Hi there,

I believe this might be a bug in the 1.5 parser

Trying to parse this:

show rsvp interface #if($tunnel-number) tunnel-te $tunnel-number #endif

I am getting this:

java.lang.NullPointerException
at org.apache.velocity.runtime.parser.Parser.Directive(Parser.java:672)
at org.apache.velocity.runtime.parser.Parser.Statement(Parser.java:320)
at org.apache.velocity.runtime.parser.Parser.IfStatement(Parser.java:1453)
at org.apache.velocity.runtime.parser.Parser.Statement(Parser.java:293)
at org.apache.velocity.runtime.parser.Parser.process(Parser.java:258)

I guess this should be a ParseException, not a NPE.

Obviously the #endif should have been #{end} but the NPE was throwing our
environment into a funny state.

I tried to submit a bug via JIRA but it didn't seem clear how to.

cheers,

josh

Hi Josh,

Yeah, that shouldn't be an NPE.   To open a bug report, go to
https://issues.apache.org/jira/browse/VELOCITY and click the "Create
New Issue" link in the menu bar along the top of that page.

Also, do you still get an NPE if you try it with Velocity 1.6?

thanks,
nathan
