------------------------------------------------
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)}}.
