Thanks, this is really useful. For once, I understand the difference between
Mauve and libjava/testsuite. I admit I could have looked into this more,
but on Win32, the activation energy is higher.

A couple of outstanding questions:

- How does one typically "certify" a patch? Do they run the testsuites
  before and after the patch and then compare the number of successes
  and failures?

- How does one run Jacks?

It would be cool to have a step-by-step guide for libjava testing similar
to this ("after you've coded your patch, do this, this and this"):

Thanks for indulging me. I'm cashing in one of my
could-have-figured-this-out-myself chips.
