Subject Re: cobertura-instrument--anyone seen this?

OK, here's the explanation, and well, if it isn't frustrating...

I'd recently rearranged my classpath. (I should have realized right away
that's what changed recently and started down that route.) Apparently, I
wasn't making available in the classpath the libraries needed by Cobertura:
log4j, asm, asm-tree, oro.

I'm using Cobertura 1.9.1. The cobertura-instrument task for that version of
Cobertura doesn't complain or give any kind of indication that those
libraries are missing from the classpath. It just silently succeeds, saying
it saved information on 0 classes. This is true even in verbose mode.

I checked if Cobertura 1.8 behaved differently. Sure enough, it started
spewing out ClassNotFoundExceptions.
