Subject [jira] [Commented] (JCR-3469) Thread interrupt may result in closed index files
Date Mon, 03 Dec 2012 11:13:58 GMT

    [ https://issues.apache.org/jira/browse/JCR-3469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13508652#comment-13508652

Marcel Reutegger commented on JCR-3469:
---------------------------------------

Looks like this is solaris specific. More background information is available here: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4385444

On Solaris the HotSpot option UseVMInterruptibleIO is enabled per default with Java 6. This
makes I/O behaviour in presence of Thread interrupts platform specific. I'll try to reproduce
the test failure on a Solaris instance...

> 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
