Description

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 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.
