Subject [jira] [Resolved] (JCR-3469) Thread interrupt may result in closed index files
Date Tue, 04 Dec 2012 10:12:59 GMT

     [ https://issues.apache.org/jira/browse/JCR-3469?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Marcel Reutegger resolved JCR-3469.

    Resolution: Fixed

I'm able to reproduce this on Solaris 11.1 (x86). In contrast to NIO, the underlying file
is not closed and subsequent queries are successful.

Updated the test to ignore the RepositoryException if the root cause is a InterruptedIOException.

> 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: http://lucene.markmail.org/thread/ea7mj2kpdvyuesss
