---------------------------------------
Summary: WindowsFS misses to remove open file handle if file is
concurrently deleted
Key: LUCENE-6499
URL: https://issues.apache.org/jira/browse/LUCENE-6499
Project: Lucene - Core
Issue Type: Bug
Components: modules/test-framework
Affects Versions: 5.1
Reporter: Simon Willnauer
Fix For: Trunk, 5.3
WindowsFs has some race conditions when files are concurrently opened and
deleted. A file might be successfully opened while concurrently deleted which
should be prevented by the WindowsFS with an IOException / access denied. The
problem is that we try to remove the leaked file handle form the internal map
on close which fails since we fail to read the key from the filesystem since it
has already been deleted. This manifests in subsequent `access denied`
exceptions even though all streams on the file are closed.
