[jira] Created: (UIMA-1201) UIMA Does Not Exit Due to
threadGroupDestroyer Thread Waiting On Daemon Threads
UIMA Does Not Exit Due to threadGroupDestroyer Thread Waiting On Daemon Threads
-------------------------------------------------------------------------------
Key: UIMA-1201
URL: https://issues.apache.org/jira/browse/UIMA-1201
Project: UIMA
Issue Type: Bug
Components: Collection Processing
Affects Versions: 2.2.2
Reporter: Stephen Duncan Jr
The threadGroupDestroyer thread is causing my application to not exit when finished processing. It's waiting on some threads from my database connection pool. Those threads are daemon threads that won't end until the JVM shuts down. The threadGroupDestroyer should not wait for daemon threads to end before destroying the thread group. The relevant code is in lines 2518-2542 of CPMEngine.java

was (Author: schor):
This is fixed in 2.3. For 2.2.2, the work-around for this is to use local reply queues with remote CAS multipliers. This isn't possible if using HTTP as the messaging protocol - in that case, please apply this patch to your 2.2.2 release.

[jira] Commented: (UIMA-1201) UIMA Does Not Exit Due to
threadGroupDestroyer Thread Waiting On Daemon Threads
Posted by "Marshall Schor (JIRA)" <ui...@incubator.apache.org>.
[ https://issues.apache.org/jira/browse/UIMA-1201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12655245#action_12655245 ]
Marshall Schor commented on UIMA-1201:
--------------------------------------
After a bit of investigation, I found that
# The shut-down code does a threadgroup {{destroy()}} call
# This call cannot be done until all the threads in the threadgroup have been stopped
There is no "safe" way to stop arbitrary threads, daemons or not. See http://java.sun.com/j2se/1.5.0/docs/guide/misc/threadPrimitiveDeprecation.html
There may be some workarounds for your particular situation, though. The best would be to arrange for the daemon threads that you start for your database connection pool to be either
* stopped by you when you detect the end of the run
* associated (when started) with a different thread group that is not a subgroup of this one.
I'm closing this as a "won't fix", but please feel free to re-open it if this analysis is incorrect.
