> I am running Tomcat apache 6.0 in windows XP. I am trying to access Transient repository.

> In very first run, I am able to open and close session for Transient repository. but
in the next run, it always throws exception "java.nio.channels.OverlappingFileLockException".
> To resolve that issue(workaround)  I have to restart the apache server. In case of very
first run, I am able to read/write from/to repository. 
> code snippet used: ( wrapper calls to class to session open and close)
> import java.io.OutputStream;
> import javax.jcr.Repository;
> import javax.jcr.Session;
> import javax.jcr.SimpleCredentials;
> import org.apache.jackrabbit.core.TransientRepository;
