Hi,
what I can add here is that at a project we run > 100'000 tests with
EclEmma on Windows. The tests run for about 10min. No issues like this
so far.
I'm pretty sure this is related to a JVM shutdown problem like the issue
Evgeny mentioned.
As a workaround you might block execution in your "last" test and
request coverage data from the coverage view manually while the JVM is
still running.
