J=C3=B8rgen L=C3=B8land commented on DERBY-3358:
--------------------------------------

Since stopMaster throws StandardException - isn't it a bit overkill to catc=
h Throwable?

+        try {
+            stopMaster();
+        } catch (Throwable t_stopmaster) {
+            //The stop master threw an exception saying the replication
+            //has been stopped already.
+            ReplicationLogger.
+                logError(MessageId.REPLICATION_MASTER_STOPPED, t, dbname);
+        }

BTW: did you mean to log the stack trace of t here or should it be t_stopma=
ster?
