[drbd-mc] LCMC 1.0.2 java NPE

[Trevor Hemsley]

I downloaded LCMC 1.0.2 to try it out. Pointed it to my existing 
DRBD/Corosync/Pacemaker cluster and had it retrieve all the details and 
then it crashed with a null pointer exception. If I fire it up now, it 
has remembered the details of the cluster and asks for my ssh passphrase 
to connect to both machines, asks for my sudo password for both nodes, 
pulls a bunch of info, paints some icons then crashes with

AppError.Text
