Description
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.
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.
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:
