Description

If a buildfile sets a system property like so:

Java.java.lang.System.setProperty("foo", "bar")

a subsequent attempt to run JUnit tests will fail with a NoClassDefFoundError for org/apache/buildr/JavaTestFilter. A minimal project which demonstrates this can be found in this gist: http://gist.github.com/460611 . Clone it and then run `buildr clean test` to replicate.

This worked in 1.3.5. It continues to work in 1.4.0 in JRuby, but not in MRI.

(Apologies for not catching this in an RC – most of my prerelease testing was with a different project that didn't do this.)
