Summary: Potential resource key clash in environments with multiple classloaders Key: UIMA-6385 URL: https://issues.apache.org/jira/browse/UIMA-6385 Project: UIMA Issue Type: Bug Components: uimaFIT Reporter: Richard Eckart de Castilho Assignee: Richard Eckart de Castilho Fix For: 3.2.1uimaFIT The {{ExternalResourceFactory}} internally generates a unique key for each resource using the method {{ExternalResourceFactory.uniqueResourceKey(String)}}. This method internally uses a static thread-safe counter which is increased for each resource. However, if we are in an environment where multiple instances of uimaFIT exists, e.g. within PEARs or OSGI environments, then it is possible that the same unique key is produced by two uimaFIT instances. It would also be possible that these keys both end up in the same resource manager and then the resources would override each other. A solution for this could be to also include some unique uimaFIT instance ID in the unique key, e.g. the {{System.identityHashCode(DISAMBIGUATOR)}}. -- This message was sent by Atlassian Jira (v8.3.4#803005)
