Dan Berindei created ISPN-6977: ---------------------------------- Summary: NumOwnersNodeCrashInSequenceTest random failures Key: ISPN-6977 URL: https://issues.jboss.org/browse/ISPN-6977 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.2.4.Final, 9.0.0.Alpha4 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Critical Fix For: 9.0.0.Beta1 The test (and {{NumOwnersNodeStopInSequenceTest}} as well) uses {{StateSequencerUtil.advanceOnInboundRpc()}}, which replaces the {{PerCacheInboundInvocationHandler}} and rewires all the components. The problem is that rewiring {{StateConsumerImpl}} causes it to create a new {{SemaphoreCompletionService}}, but there's no synchronization when reading the field, a "background" task could finish on another thread and release the permit on the old {{SemaphoreCompletionService}} instance. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
