[jboss-jira] [JBoss JIRA] (WFCORE-4609) Core threads in EnhancedQueueExecutor might timeout below core pool size even if allowCoreTimeOut is false

Miroslav Novak created WFCORE-4609: -------------------------------------- Summary: Core threads in EnhancedQueueExecutor might timeout below core pool size even if allowCoreTimeOut is false Key: WFCORE-4609 URL: https://issues.jboss.org/browse/WFCORE-4609 Project: WildFly Core Issue Type: Bug Components: IO Affects Versions: 10.0.0.Beta2 Reporter: Miroslav Novak Assignee: Flavia Rainone I can see unexpected behavior in EnhancedQueueExecutor [1]. Even when I set allowsCoreThreadTimeOut to false, sometimes happens that pool size goes below core size by a few threads. Test scenario: - create EnhancedQueueExecutor with coreSize=3, maxSize=6, allowsCoreThreadTimeOut=false, keepAliveTimeout=1000ms - submit 6 threads into executor and wait until all are running so maxSize is reached - allow all threads to finish and wait some time for threads to timeout Expected result is that poolSize will be 3 as coreSize=3 but sometimes happens that poolSize is 2 or 1. This might not be a bug as EnhancedQueueExecutor estimates its pool size and might allow to timeout more threads than coreSize. I'm creating this jira so it's explained for future reference.
