I cannot think of any reason why any Apache project should be
concerned with obfuscation or decompilation. We are open source, and
our dependencies are open source. Junit is a testing tool, so you
should never need to redistribute it, just arrange to have it
available for builds, and maven or ant/ivy will do that, and the same
with emma, which is another development tool.

There are many examples of this at other project. If it would be
helpful, I could join the dev list to help with the discussion here.
