[infinispan-issues] [JBoss JIRA] (ISPN-9907) NullPointerException when async operations share a LocalTransaction

NullPointerException when async operations share a LocalTransaction ------------------------------------------------------------------- Key: ISPN-9907 URL: https://issues.jboss.org/browse/ISPN-9907 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 10.0.0.Alpha3, 9.4.6.Final Reporter: Dan Berindei Priority: Major Labels: testsuite_stability Fix For: 10.0.0.Beta1 Attachments: ISPN-4075_timestamps_improvements_20190128-1450_DistFineGrainedAtomicMapAPITest-infinispan-core.log.gz I'm not convinced we should support invoking multiple cache operations bound to the same TM transaction in parallel, but {{FineGrainedAtomicMapProxyImpl.removeAll()}} calls {{AdvancedCache.removeAsync()}} for each key in the map and then blocks to wait for all of them. Because the {{lookedUpEntries}} map in {{LocalTransaction}} is not synchronized, this makes {{DistFineGrainedAtomicMapAPITest}} fail randomly with a {{NullPointerException}}: {noformat} 15:05:36,898 ERROR (testng-Test:[]) [TestSuiteProgress] Test failed: org.infinispan.atomic.DistFineGrainedAtomicMapAPITest.testReplicationPutAndClearCommit java.lang.NullPointerException: null at
