[jira] Created: (UIMA-398) test case intermittently fails running
Java 6 - with a hang: uimaj-core,
org.apache.uima.analysis_engine.impl.MultiprocessingAnalysisEngine_implTest
test case intermittently fails running Java 6 - with a hang: uimaj-core, org.apache.uima.analysis_engine.impl.MultiprocessingAnalysisEngine_implTest
----------------------------------------------------------------------------------------------------------------------------------------------------
Key: UIMA-398
URL: https://issues.apache.org/jira/browse/UIMA-398
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.1
Environment: Sun Java 6_01
Reporter: Marshall Schor
The failure is intermittent. It fails the first time running (for me) from a reboot, but runs after that. The failure occurs in the test where it does a threads[i].join(); and happens when i = 0. I found this out by changing the join() to join(10000), and then inserting:
if (threads[i].isAlive()) {
System.err.println("timeout waiting for thread to complete " + i);
fail("timeout waiting for thread to complete " + i);
}

[jira] Commented: (UIMA-398) test case intermittently fails running

Marshall Schor commented on UIMA-398:
-------------------------------------
The test case fails when doing the following:
1) set up an instance of MultiprocessingAnalysisEngine_impl with a pool of 3
2) start 4 threads (4 > 3); each gets a new CAS and calls the process method on the same MultiprocessingAE instance
3) The failure comes when the process call is using the form with the result specification.
It seems odd that one thread calling process would check out *all* instances to set the result specifications on all the instances in the pool (that's what's implemented for setResultSpecification).
This is the cause of the hang. If one thread starts setting result specification, it starts checking instances out of the pool, one by one. If another starts also, then they lock each other out (one might have 2, the other 1, and they'll just sit there waiting to get the rest).
