So with JDK 8 (64 bit where possible), the tests are all passing on the systems I tested: FreeBSD 11.0 x64, Ubuntu 16.04 (x32 and x64), and Windows 10 x64.

I have two tests consistently in error with OpenJDK 7 (and Maven 3.5.0-alpha-1), at least on Ubuntu:

Failed tests:
invokeRuntimeException(org.apache.maven.surefire.its.jiras.Surefire141PluggableProvidersIT): expecting non-empty, but it was empty invokeReporterException(org.apache.maven.surefire.its.jiras.Surefire141PluggableProvidersIT): expecting non-empty, but it was empty

They are also failing when ran individually if passing -Dit.test=Surefire141PluggableProvidersIT to the Maven command.

I will test with a JDK 6 right now.

Same errors with Oracle JDK 6, and Maven 3.2.5.

Yes, there are a lot of tests 1200 altogether. For instance I have 4 Cores of CPU and the build takes 45 minutes. In your case 1 Core of Virtual CPU which makes the difference. Tuning of JVM is also important. Not too much and not too less of Xmx cca 700 MB and the same or more for permanent part
of memory. I think JVM does not run in server mode if RAM < 2GiB even if
you have x64.

Yes, I finished running the tests multiple times on FreeBSD with Maven
3.5.0-alpha-1, and they are all passing! The tests were however painfully slow (more than 4 hours), it might be an issue with my VM (64 bits, only
has 1 Go of RAM and 1 vCPU), I'll see how much time it takes with those
same characteristics, but on Ubuntu.

I will be running them again on Windows and Ubuntu with JDK 7 and 8 over
the next few days.

Hi Guillaume Boué,

Have you found a spare time to test the branch?

Cheers

Hi,
I finished setting up a FreeBSD VM with a couple of Maven and JDK
versions, so I'll be testing this extensively (on Ubuntu as well). Thanks
for the work!

Hi All,
The new branch SUREFIRE-1342 solves an issue when entire testset
completed
however the surefire's forked JVM finished printing serious issue. We
know
that the JVM did not crash however it looks so:

The forked VM terminated without saying properly goodbye. VM crash or
System.exit called ?


The problem is solved in the branch and ready to be tested.

The entire problem was concurrency issue where the forked JVM sent "bye" event to the Maven process via stdout but Maven process has not drained shared memory yet and Maven process was therefore slower to receive the event than the forked process which exited. Due to the "bye" event was
not
determined by Maven process in particular time, this error came up.
We implemented ACK command which confirms such event has been received
by
Maven process. The shared memory is drained directly by Maven process.

Cheers
Tibor
