Subject [jira] [Commented] (LUCENE-2822) TimeLimitingCollector starts thread in static {} with no way to stop them
Date Wed, 26 Oct 2011 06:35:36 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13135749#comment-13135749
] 

Torsten Krah commented on LUCENE-2822:
--------------------------------------

Some workaround - until this one is resolved - to stop the thread (e.g. in a container shutdown
callback) may be this one using reflection:

Thread t = (Thread) FieldUtils.readDeclaredStaticField(TimeLimitingCollector.class, "TIMER_THREAD",
true);
      if (t != null && t.isAlive()) {
        t.interrupt();
        t.join(1000);
      }

Little bit ugly but theres no other way yet.

> If you even do Class.forName("TimeLimitingCollector") it starts up a thread in a static
method, and there isn't a way to kill it.
> This is broken.
