---------------------------------------
Summary: NIOFS and SimpleFSDirectory may leak files if
Channel#size() throws an exception
Key: LUCENE-7349
URL: https://issues.apache.org/jira/browse/LUCENE-7349
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 6.1, 6.0
Reporter: Simon Willnauer
Fix For: 6.2, 6.1.1
We call Channel#size() inside the NIOFSIndexInput ctor but ignore the fact that
it can throw an IOException. I ran into this due to a ClosedByInterrupt
exception which we explicitly state don't support. This can also happen due to
an IOException and we should at least not leak a file handle in such a case.
