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)
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.
