[ https://issues.redhat.com/browse/WFCORE-3948?page=com.atlassian.jira.plug... ] Paul Ferraro edited comment on WFCORE-3948 at 12/6/19 6:39 AM: --------------------------------------------------------------- [~brian.stansberry] FYI, this change has broken some DUP logic in wildfly full. The new collection type does not support all of the optional list operations that were formerly supported by the old type. I'll file follow-up jiras to fix these as I find them. e.g. {noformat} 2019-12-06 12:10:03,346 ERROR [org.jboss.as.server.deployment] (MSC service thread 1-1) WFLYSRV0043: Deployment unit processor org.jboss.as.connector.deployers.ra.processors.CachedConnectionManagerSetupProcessor@4786eb0d unexpectedly threw an exception during undeploy phase POST_MODULE of deployment "SyncCircuitBreakerDisabledTest.war": java.lang.UnsupportedOperationException at java.util.concurrent.CopyOnWriteArrayList$COWIterator.remove(CopyOnWriteArrayList.java:1178) at java.util.Collections$CheckedCollection$1.remove(Collections.java:3079) at java.util.Collection.removeIf(Collection.java:415) at org.jboss.as.connector.deployers.ra.processors.CachedConnectionManagerSetupProcessor.undeploy(CachedConnectionManagerSetupProcessor.java:75) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.safeUndeploy(DeploymentUnitPhaseService.java:245) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.stop(DeploymentUnitPhaseService.java:238) at org.jboss.msc.service.ServiceControllerImpl$StopTask.stopService(ServiceControllerImpl.java:1795) at org.jboss.msc.service.ServiceControllerImpl$StopTask.execute(ServiceControllerImpl.java:1764) at org.jboss.msc.service.ServiceControllerImpl$ControllerTask.run(ServiceControllerImpl.java:1559) at org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1982) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1486) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1377) at java.lang.Thread.run(Thread.java:748) {noformat} was (Author: pferraro): FYI, this change has broken some of the logic in wildfly full. e.g. {noformat} 2019-12-06 12:10:03,346 ERROR [org.jboss.as.server.deployment] (MSC service thread 1-1) WFLYSRV0043: Deployment unit processor org.jboss.as.connector.deployers.ra.processors.CachedConnectionManagerSetupProcessor@4786eb0d unexpectedly threw an exception during undeploy phase POST_MODULE of deployment "SyncCircuitBreakerDisabledTest.war": java.lang.UnsupportedOperationException at java.util.concurrent.CopyOnWriteArrayList$COWIterator.remove(CopyOnWriteArrayList.java:1178) at java.util.Collections$CheckedCollection$1.remove(Collections.java:3079) at java.util.Collection.removeIf(Collection.java:415) at org.jboss.as.connector.deployers.ra.processors.CachedConnectionManagerSetupProcessor.undeploy(CachedConnectionManagerSetupProcessor.java:75) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.safeUndeploy(DeploymentUnitPhaseService.java:245) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.stop(DeploymentUnitPhaseService.java:238) at org.jboss.msc.service.ServiceControllerImpl$StopTask.stopService(ServiceControllerImpl.java:1795) at org.jboss.msc.service.ServiceControllerImpl$StopTask.execute(ServiceControllerImpl.java:1764) at org.jboss.msc.service.ServiceControllerImpl$ControllerTask.run(ServiceControllerImpl.java:1559) at org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1982) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1486) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1377) at java.lang.Thread.run(Thread.java:748) {noformat} -- This message was sent by Atlassian Jira (v7.13.8#713008)
