Subject [jira] Commented: (DERBY-3447) Shutdown on a database without stopping replication hangs
Date Sun, 16 Mar 2008 04:42:25 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12579160#action_12579160

V.Narayanan commented on DERBY-3447:
------------------------------------

When I found out about Derby-3451 I was thinking why the quit without
starting replication does not seem to hang. I found out that it does not
hang because the other threads used in derby are Daemon threads .

see BaseMonitor#getDaemonThread (line no 2080)

relevant lines

Thread t =  new Thread(daemonGroup, task, "derby.".concat(name));
t.setDaemon(true);

found "The Java Virtual Machine exits when the only threads running are all daemon threads."
here http://java.sun.com/j2se/1.3/docs/api/java/lang/Thread.html#setDaemon(boolean)
