Thanks!

I've looked again at the stack trace, and you're correct - it's Maven
that is complaining.

Meanwhile I've found a way round the issue for Commons projects:

-Pjava-1.5 -DJAVA_1_5_HOME=/home/jenkins/tools/java/latest1.5

[The java-1.5 profile sets the java version for compile and test
assuming that JAVA_1_5_HOME is set appropriatel]

So long as 1.5 is always at that location we should be good.
