[platform-releng-dev] Test failures with Java 1.7 when tests must be exe

[Markus Keller <markus_keller@xxxxxxxxxx>]

A likely cause for test failures with Java
1.7 is that the execution order of tests is no longer predictable.

I think that's e.g. what causes the
p2 failures. This is hard to nail down or reproduce, since the order is
basically random now.

To ensure a consistent order, a test
suite needs to define the order. I just filed https://bugs.eclipse.org/bugs/show_bug.cgi?id=369818
to add an OrderedTestSuite class that can be used to achieve this. This
should become available in M6.

I suggest to live with the test failures
in M5 if they only happen on 1.7 and are likely due to the random execution
order.

I'm looking at the p2 tests. However, nothing has changed
here and each build it appears something different has failed. The only
(somewhat) consistent thread I see is that packed things sometimes have
trouble being processed.

Also, Kim just mentioned that we just started running
with 1.7 on our windows machine. I don't know if this is the cause or not.
I'll keep digging.

Cheers,
Ian

The Ant test failures are intermittent and do not affect the quality of
the build.

The failure is being tracked here: https://bugs.eclipse.org/369837
