------------------------------------
Summary: protect UIMA Class loader in multi-threaded get resource
contexts
Key: UIMA-5741
URL: https://issues.apache.org/jira/browse/UIMA-5741
Project: UIMA
Issue Type: Improvement
Components: Core Java Framework
Affects Versions: 3.0.0SDK, 2.10.2SDK
Reporter: Marshall Schor
Assignee: Marshall Schor
Fix For: 3.0.1SDK, 2.10.3SDK
I have seen one case where multiple threads were being used where a UIMA Class
Loader was being used to load a resource (Type system Descriptor -> type System
was resolving an "import by name"), where the getResource returned (only once)
a spurious "null" result.
This is likely due to some multithreading issue in get Resource. Add a sync
using the same multi-threaded parallel approach used for class loaded, to
getResource, to protect against this case.
