Kahadb archiving does not work accross different physical file systems

Issue

• Cannot archive Journal files in a separate file system
• We cannot use a separate file system to host the A-MQ archived Journal files, e.g. in activemq.xml configuration :

<kahaDB directory="${karaf.data}/live" archiveDataLogs="true" directoryArchive="${karaf.data}/archive"...

where ${karaf.data}/live and ${karaf.data}/archive are not on the same file system.
If the live and archive file systems are different, we get the below error when a Journal file has to be moved to the archive:
