Add to that, that most basic tests usually expect a client/server JVM
for which Zero is an odd ball. Also, due to it's weaker performance
many tests time out and fail rather than conditionally setting longer
timeout values. It's a rather large and cumbersome process to make the
whole test suite Zero compatible.

It's more of a case of going through every test one by one and figuring
out whether a "failure" is a test issue, a Zero issue, or an
environmental issue.
