Subject [jira] [Commented] (LUCENE-3785) Replace ant macros for running concurrent tests with ant-junit4.

jvm-crash resilience (I wrote tests that actually crash a slave jvms to make sure such an
event is reported appropriately),

Its really annoying with our current setup that you have no clue which test the jvm crashed
in... you just see (crashed)

> ant-junit4 is an ANT task for running tests in parallel (on slave JVMs). Its advantages
over the current macros:
> - dynamic load balancing based on historical test runs and current execution (job-stealing),
> - jvm-crash resilience (I wrote tests that actually crash a slave jvms to make sure such
an event is reported appropriately),
> - nicer console reporting (no need for syserrs on LuceneTestCase level).
> More documentation and info will follow as I roll out a patch.
