Geoff Macartney created BROOKLYN-378:
----------------------------------------
Summary: Failures in builds on stop related tests
Key: BROOKLYN-378
URL: https://issues.apache.org/jira/browse/BROOKLYN-378
Project: Brooklyn
Issue Type: Bug
Affects Versions: 0.10.0
Reporter: Geoff Macartney
Priority: Minor
Intermittently the test SoftwareProcessEntityLatchTest.testStopLatchBlocks is
failing.
The failures were seen in brooklyn-master-build, which is pinned to a specific
machine,
haven't observed it *yet* in server-master job.

h4. Steps to reproduce?
So far I have been unable to reproduce the problem. I have tried to reproduce
it with the following steps:
1. Running the test with a restricted environment. Used a Vagrant box with 1
CPU and RAM set at 1496Mb.
2. Adding CPU stress to the machine. Added the 'stress' tool to the machine
{{sudo apt-get install -y stress}} and ran with up to four stressors {{stress
-c 4 -t 3600}}
while executing the unit test. The tool restricts Java to about 45% of the CPU
at most. (Oddly this doesn't depend on the number of stressors running.)
3. Jittering threads. Added jitter to the test with
{code}
mvn surefire:test
-Dtest=org.apache.brooklyn.entity.software.base.SoftwareProcessEntityLatchTest#testStopLatchBlocks
-Dbrooklyn.executionManager.jitterThreads=true
-Dbrooklyn.executionManager.jitterThreads.maxDelay=1000
{code}
4. Added {{@Test(invocationCount = 20)}} to the test.
5. Did the iteration count while running stress tool. This did give a timeout
on the first iteration only, but not on the stop latch, rather on the
{{assertAttributeEqualsEventually(timeoutConfig, app, SERVICE_UP, true);}} on
the app. The rest of the tests succeeded with timings:

6. Added multiple successive iterations of setting and releasing the stop latch
within the test. Testing with 200 iterations under stress didn't reproduce the
issue.
7. Updated the test to add multiple child entities and stop them in parallel
tasks. Testing with 200 iterations under stress didn't reproduce the issue.
8. All of the above: stress + jitter (up to 200ms) + 200 serial iterations or
20 parallel. Again both tests succeeded.
I haven't yet tried to repoduce the failure in
SoftwareProcessStopsDuringStartTest.
