          The NPE seems to stem from this code:

          //add active buffers to dirty buffer list
          //to flush to the disk.
          logOut.switchLogBuffer();
           

          so the variable "logOut" must be null.

          Thanks, Myrna. Unfortunately that jar contains logs from an insane derby jar, so it doesn't show the line numbers. This is the segment I am interested in (from the slave's derby.log):

          Hmm, no it seems the slave will try to reconnect to the master forever, unless it gets closed down, cf. SlaveController#handleDisconnect.

          I suspect the NPE comes from FileToLog#logOut being null, but I don't yet have a theory how that can happen in this scenario. When the slave detects that the master is gone, could there be some kind of race which thread stops the slave? [the test does a) kill the master, b) stop slave], cf. line 91 in ReplicationRun_Local_3_p5.

          I am not sure the first NPE is related, though, just an observation. The variable "dd" (data dictionary) is null when stopping here, cf. BasicDatabase#stop.
          But it happens as internalStopReplicationSlave shuts down the database after having verified that the slave has stopped, cf. line 1034 in EmbedConnection.

The variable "dd" (data dictionary) is null when stopping here, cf. BasicDatabase#stop. But it happens as internalStopReplicationSlave shuts down the database after having verified that the slave has stopped, cf. line 1034 in EmbedConnection.

          Saw the same exception stack in testReplication_Local_StateTest_part1_1, running trunk on Solaris 11, Java 6, using Knut's parallel test runner, this time with sane build, cf. derby.log from slave uploaded "db_slave-derby.log". NPE in LogToFile.flush when stopping slave.

          These instabilities in the replication tests are very timing dependent
          in my experience. Not sure what sets this one off.

          I have saved the database images and log files bundle from this test (2Mb, a bit much to upload, so please contact me if you want to have a look at it).
