Marcel Reutegger created JCR-3469:
-------------------------------------
Summary: Thread interrupt may result in closed index files
Key: JCR-3469
URL: https://issues.apache.org/jira/browse/JCR-3469
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 2.4
Reporter: Marcel Reutegger
Priority: Minor
Interrupting a thread, which is currently performing I/O on Lucene index files,
may result in closed index files. Jackrabbit versions prior to 2.4 didn't have
that problem because only with the update of Lucene to 3.0.3 in Jackrabbit 2.4
the underlying default for the FSDirectory in Lucene changed from
SimpleFSDirectory to NIOFSDirectory. The latter uses a FileChannel to perform
concurrent read operations on a single channel, but because of the way how
FileChannel is specified an interrupt will result in the FileChannel to be
closed.
This was also discussed on the Lucene mailing list. See:
