Marshall Schor updated UIMA-4263: --------------------------------- Affects Version/s: (was: 2.7.0SDK) > thread safety problem in uimaj-core code causing occasional hang > ---------------------------------------------------------------- > > Key: UIMA-4263 > URL: https://issues.apache.org/jira/browse/UIMA-4263 > Project: UIMA > Issue Type: Bug > Components: Core Java Framework > Reporter: Marshall Schor > Assignee: Marshall Schor > Priority: Minor > Fix For: 2.7.0SDK > > > The class AnalysisEngineManagementImpl (which implements JMX instrumentation) > uses a static set to remember what names have been used for "root" MBeans. > Access to this set is not synchronized, so it's possible for two threads to > try and simultaneously update this set. Check for other static sets/maps > with this problem, too. Either convert this to a synchronized access, or use > one of the concurrent maps/sets. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
