I am a bit confused why it is giving the "eval failed..." message though.
It's an NPE, but beyond that I'm not sure what's happening.
The branch_3x Maven job compiles under a 1.5 JDK, then runs tests via Maven's Surefire plugin under a 1.6 (OpenJDK) JVM.
These tests appear to pass on the Solr_3x job under the same 1.6 JVM, though, so there's something weird going on here. (The Solr_3x job runs under Ant, but I'm not sure why the Ant/Maven difference would be the cause of this.)
Why don't you make the fix you've proposed and I'll look later to see if there is something less-blunt we can do. Sound ok?
Sure, I'll commit those changes now.
