Ended up chasing our tail for a while today because the ant build.xml in the 3.3.1 distribution on the website has version is actually "3.3.2-dev". Any particular reason for that? The jar included in the distribution is obviously labeled correctly, and the version number in its manifest is 3.3.1, so it appears that the build.xml was modified and bundled up for distribution after the binary was built. Not sure if it's worth fixing in the distribution, but thought I'd at least mention it.
