>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Message Store
>    Affects Versions: 5.1.0
>         Environment: WinNTFileSystem
> jdk 1.6_05
>            Reporter: Tuomas Kiviaho
>            Assignee: Rob Davies
>             Fix For: 5.3.0

> I've been getting the following exception
> Caused by: java.io.FileNotFoundException: activemq-data\localhost-kahastore\lock (The system cannot find the path specified)
> 	at java.io.RandomAccessFile.open(Native Method)
> 	at java.io.RandomAccessFile.<init>(RandomAccessFile.java:212)
> 	at org.apache.activemq.kaha.impl.KahaStore.initialize(KahaStore.java:476)
> I assume that changeset 661435 <http://fisheye6.atlassian.com/changelog/activemq?cs=661435> was aimed to fix the problem following problem:
> Error in directory.mkdirs is masked and can result in FileNotFoundException when creating tmp_storage directory <http://open.iona.com/issues/browse/MB-360> 
> I verified that there is no problem in creating the parent directories, but filesystem thinks that directory doesn't exists after it has been created succesfully. After little more digging I stumbled upon the following:
> File.getAbsolutePath() is incorrect if "user.dir" is set on the command line <http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4117557>
> There is some more information about using canonical form at Mule project <http://mule.mulesource.org/jira/browse/MULE-1112> and I found out that using getCanonicalFile() does indeed work.
> As a patch I suggest that all file/directory related methods at IOHelper would return (canonical) File instead of String. 
> Other not so intrusive possibility would be to change XBeanBrokerService.
