Re: [Hsqldb-user] Deadlock (kind of) at Server shutdown

[fredt <fr...@us...>]

Obviously the ServerConnection.close() method is called twice when there are multiple open connections and a shutdown is called. This can be ignored, as there is no further code that the thread has to execute.

Will review for the next version.

  I've been playing with the new beta that Fred sent me, and my original problem with the locking has not come back. However, I do get a different error now, and since I never had this error before, and since the new error occurs in the same spot as the old one, I thought that maybe the new fix is affecting something else... 

  My program does run without any problems (that I can see), but in my process output I see the following error message, (same error, repeats itself 4 times; this has happened to me twice that it would repeat the same error, 4 times)

  Exception in thread "HSQLDB Connection @1556f4c" java.lang.NullPointerException
