[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-4989) Make Statistics concurrent safe when Java 5 is present (Alex Snaps)

[Alex Snaps (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4989?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alex Snaps updated HHH-4989:
----------------------------

    Attachment: conStat4.patch

It wasn't a dead lock (as the point of these stats is to be non blocking), but obviously in
for (long old = executionMaxTime.get(); (time > old) && !executionMinTime.compareAndSet(old, time); old = executionMaxTime.get());

The compareAndSet will never succeed and run in a loop for ever!
conStat4.patch fixes that. Did test runs locally and it all passes now (core and annotations).
Sorry about that... While I'll blame it on subversion screwing up diffs though ;)
