> In some circumstances it is possible that lock is not released in VersionManager.checkin method.
> There is following block of code in checkin nethod :
>         aquireReadLock();
>         try {
>               .....
>         } catch (IllegalStateException e) {
>             releaseReadLock();
>             throw new RepositoryException("Unable to start edit operation.");
>         }
> Lock release should be in finally block to make sure that lock is released when unexpected exception is thrown.
> In our environment we are getting NPE in mentioned block of code, it results in persisten lock. 
> No versioning operation is possible and our application server is running ot of threads (all threads are locked).
