[jira] [Commented] (CAMEL-9826) MongoDB consumer could potentially block during shutdown

["Raúl Kripalani (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-9826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15228906#comment-15228906 ] 

Raúl Kripalani commented on CAMEL-9826:
---------------------------------------

Quick question. Have you seen this actually happening?
* The keepRunning flag is volatile.
* The cursor is closed by the shutdown thread, therefore the call to `cursor.hasNext()` in the while guard should unblock and either give an opportunity for the guard to evaluate the new value of keepRunning (false) or throw an exception, unless there's a bug in the MongoDB driver and `cursor.hasNext()` never returns even when another thread has closed the cursor.

> This should be using a CountDownLatch to await for the stop to complete so there is no endless while loop.
