----------------------------------
Summary: Destroy the ResourceManager on destroy of a pear
Key: UIMA-5935
URL: https://issues.apache.org/jira/browse/UIMA-5935
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.10.3SDK
Reporter: Philipp Butz
Attachments: Screenshot from 2018-12-18 08-34-10.png
This bug is related to bug UIMA-5799 . The bug seems not completely fixed,
since the files are still being accessed after trying to delete them. This
behavior can be shown by the tool 'lsof' (see screenshot). There seems still to
be access to the resources of a pear on the file system, which denies the
complete deletion on the file system after uninstalling it (they are marked as
deleted but are not actually removed).
Potential cause:
The class PearAnalysisEngineWrapper creates and caches resource managers. The
elements in that Cache (Java map) are never explicitly removed, not even in the
destroy method.
