+	* orbsvcs/orbsvcs/LoadBalancing/LB_Random.cpp (next_member):
+	  (_tao_next_member):
+
+	  Refactored random member selection code into a TAO-specific
+	  static method.  This is possible since this random load
+	  balancing strategy implementation is stateless.  This allows
+	  other strategies to reuse the random member selection code with
+	  instantiating the TAO_LB_Random class.
+
+	* orbsvcs/orbsvcs/LoadBalancing/LB_LeastLoaded.cpp (next_member):
+
+          No loads have been reported for any of the locations the object
+	  group members reside at.  If no loads have been reported to the
+	  LoadManager, adaptive load balancing decisions cannot be made.
+	  Fall back on a non-adaptive strategy, such as the Random load
+	  balancing strategy, instead.  The Random load balancing strategy
+	  is used since it is very lightweight and stateless.
