Subject [jira] Commented: (JCR-2767) Database connection leak with DBCP, MySQL, and Observers
Date Mon, 04 Oct 2010 22:29:33 GMT

    [ https://issues.apache.org/jira/browse/JCR-2767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12917806#action_12917806
] 

Christian Trimble commented on JCR-2767:
----------------------------------------

The connections that are being abandoned code from line 802 in org.apache.jackrabbit.core.journal.DatabaseJournal.
 This class has an instance variable of type org.apache.jackrabbit.core.util.db.ConnectionHelper
that it treats as a thread safe object.  However, the batch mode features of this class do
not appear to be thread safe.  I have prepared a patch that makes the batch mode features
of the ConnectionHelper class by moving its batchConnection into a thread local variable.
