Seems to be a problem with a deadlock when running tests

Old Forum
1

We have a multi module build with about 90 modules where there are intermittent problems with tests hanging inside Gradle code, specifically AsyncDispatch and AsyncReceive.

This has never happened with my MacBook Pro, but one of my colleagues has a Windows 7 machine where it happens almost all the time. Another colleague has a Windows XP where it happens more sporadically, typically on full builds, but not partial builds. It is always in the same module for both of them: the one with the most tests, about 1300, but not on the same test.

We are all running Gradle 1.0-milestone-6 and Java 1.6; they are running without the daemon and I with the daemon. They have tried with the daemon too, but it does not help.

Judgin by the thread dump, it does seem to hang in Gradle test code. Have you seen anything like this before?

I have seen this sometimes when running our performance test suite for Gradle. It seems to be related to the number of tests. Haven’t figured out the cause of the problem, yet. Will look into it.

All the threads are hanging in ‘LockSupport.park(…)’, so when searching for this, I found a blog entry that describes an old VM bug which arises from weak memory models.

This bug should have been fixed, but when trying “the fix” (’-XX:+UseMembar’), the problem almost disappeared. That is, it still happens from time to time on the Windows 7 machine.
