[jboss-jira] [JBoss JIRA] (JGRP-1872) Table: purge() with incorrect seqnos moves HD/LOW back

[Bela Ban (JIRA)]

     [ https://issues.jboss.org/browse/JGRP-1872?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban updated JGRP-1872:
---------------------------
    Description: 
When we have a Table with {{low=40, hd=40, hr=45}} and receive a {{purge(30,true)}}, then the table will be {{low=30,hd=30,hr=45}}.
This only happens with parameter {{force}} being {{true}}.
This doesn't cause any bugs, but until the next (correct) {{purge()}} is invoked, the table will show and incorrect number of missing messages.

SOLUTION: add the check to the start of {{purge()}}:
{code}
if(seqno <= low) // perhaps check for force as well
    return;
{code}
