[jboss-jira] [JBoss JIRA] (JBRULES-3616) ConcurrentModificationException in AbstractRuleBase.removePackage

[Lukas Stampf (JIRA)]

     [ https://issues.jboss.org/browse/JBRULES-3616?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lukas Stampf updated JBRULES-3616:
----------------------------------

    Description: 
At AbstractRuleBase.removePackage:

//and now the rule flows
{code}
final Map flows = pkg.getRuleFlows();
for (final Iterator iter = flows.keySet().iterator(); iter.hasNext();) {
     removeProcess( (String) iter.next() );
}
{code}
At AbstractRuleBase.removeProcess
{code}
this.pkgs.get(process.getPackageName()).removeRuleFlow(id);
{code}
removeProcess removes an object from the Map referenced by the flows variable in removePackage. Since the iterator is based on this variable it leads to a ConcurrentModificationError at iter.next().
