I think I know what's going on. Carrot2 has a dependency on Simple XML
framework, but the JAR is not needed at runtime in Solr. Javac 1.6 issues
warnings about missing annotations during compilation, but compilation
completes fine. Javac 1.5 seems to fail, so the build process will probably
need to download Simple XML dependency (it's LGPL) at least for compilation.
For the peace of mind we may keep Simple XML in runtime as well, though I've
tested that when using Carrot2 in Solr Simple XML classes are not needed.

The download link for Simple XML we need would be:
