Code Issues Proposed changes

Fix lazy initialization of non-volatile static field in GerritLauncher

Browse Source 
The `myHome` static member of GerritLauncher is lazy initialized in
the `getHomeDirectory` method.

According to FindBugs:

   Because the compiler or processor may reorder instructions, threads
   are not guaranteed to see a completely initialized object, if the
   method can be called by multiple threads.

Fix this by declaring the member as 'volatile'.
