Are you sure you were really using private static final? Static
finals are initialized when the class loads and will never change as
long as that class remains loaded. All threads would be seeing the
same value the entire time.

The other code you showed can have a race condition in that first
thread that assigns status may not have reconciled its local copy of
the new Status object by the time the second thread tries to access
it. You would need to synchronize both accesses or use volatile to
keep them in sync.

You are almost certainly not running into an HTC error.
