--------------------------------------
Summary: NIOFSDirectory sometime doesn't work on windows
Key: LUCENE-7582
URL: https://issues.apache.org/jira/browse/LUCENE-7582
Project: Lucene - Core
Issue Type: Bug
Components: core/store
Affects Versions: 5.3.1
Environment: Windows 10, 32 bits JVM
Reporter: Kevin Senechal
Hi!
I've an error using lucene on windows. I already post a question on modeshape
forum (https://developer.jboss.org/thread/273070) and it looks that
NIOFSDirectory is not working well on windows as described in the java
documentation of this class.
{quote}NOTE: NIOFSDirectory is not recommended on Windows because of a bug in
how FileChannel.read is implemented in Sun's JRE. Inside of the implementation
the position is apparently synchronized. See here for details.{quote}
After reading the linked java issue
(http://bugs.java.com/bugdatabase/view_bug.do?bug_id=6265734), it seems that
there is a workaround to solve it, use an AsynchronousFileChannel.
Is it a choice that has been made to not use AsynchronousFileChannel or will it
be a good fix?
You'll find the complete stacktrace below:
