> Project: Lucene - Java
> Issue Type: Bug
> Components: core/store
> Affects Versions: 3.4, 3.5
> Environment: Mac OS X 10.7, JDK 1.6
> CentOS 5, JDK 1.7u1
> Reporter: Yaokai Jiang

> When the NativeFSLock releases, it deletes the lock file after lock release.
> In a concurrent situation, it is possible for another thread or process to
> acquire the lock before the delete happens. Any other third thread or process
> will then be able to recreate the lock file and acquire the lock while a lock
> is already held on the deleted file.
