Artemis file locking not released

[Gunawan, Rahman (GSFC-703.H)[Halvik Corp]]

I'm using Artemis 2.19.1.  I'm using share file configuration and testing a 
scenario where the primary Artemis server is isolated from the network by 
disabling the network card.  Because the primary server lost communication to 
NFS, the file is never unlock and the backup server is always waiting for the 
lock.  When we enable the network card in primary server, the primary server is 
completely down.  Below is the primary server log:
"Reference Handler" Id=2 WAITING on java.lang.ref.Reference$Lock@64b6b3fc
        at java.lang.Object.wait(Native Method)
        -  waiting on java.lang.ref.Reference$Lock@64b6b3fc
        at java.lang.Object.wait(Object.java:502)
        at java.lang.ref.Reference.tryHandlePending(Reference.java:191)
        at java.lang.ref.Reference$ReferenceHandler.run(Reference.java:153)

Is this bugs in Artemis share file configuration?
