[jboss-jira] [JBoss JIRA] (WFLY-6540) Batch thread pool keepAlive setting seems to be ignored

Batch thread pool keepAlive setting seems to be ignored ------------------------------------------------------- Key: WFLY-6540 URL: https://issues.jboss.org/browse/WFLY-6540 Project: WildFly Issue Type: Bug Components: Batch Affects Versions: 10.0.0.Final Reporter: Martin Kouba Assignee: James Perkins Maybe I'm missing something but although the default _keepAlive_ is set to 30 seconds, the threads seem to run indefinitely - see also steps to reproduce. Snippet from the default config file: {code} <thread-pool name="batch"> <max-threads count="10"/> <keepalive-time time="30" unit="seconds"/> </thread-pool> {code} Anyway, the {{UnboundedQueueThreadPoolService}}, or the underlying {{JBossThreadPoolExecutor}} respectively, used by the Batch subsystem is using the same {{corePoolSize}} and {{maximumPoolSize}} and it seems the core threads are not allowed to time out, i.e. {{org.jboss.threads.JBossThreadPoolExecutor.setAllowCoreThreadTimeout(boolean)}} is not used. Moreover, a {{JBossThreadPoolExecutor.setAllowCoreThreadTimeout(boolean)}} invocation would probably result in an infinite loop: {code} public void setAllowCoreThreadTimeout(final boolean allow) { setAllowCoreThreadTimeout(allow); } {code} should be replaced with: {code} public void setAllowCoreThreadTimeout(final boolean allow) { allowCoreThreadTimeOut(allow); } {code} Given that {{JBossThreadPoolExecutor}} is used by more subsystems this issue may affect other subsystems as well.
