[jboss-jira] [JBoss JIRA] Commented: (JGRP-643) ClassConfigurator.getInstance() not thread safe

[Bela Ban (JIRA)]

    [ http://jira.jboss.com/jira/browse/JGRP-643?page=comments#action_12391192 ] 
            
Bela Ban commented on JGRP-643:
-------------------------------

Why is this an issue ? The static method is called only *once* with init=true, by the ProtocolStack. All other calls are *NOT* initializing it.
So there is no concurrent invocation of this method with init=true

> Creating 2 or more JChannels simultaneously could result in multiple ClassConfigurators being created and inited at once or a ClassConfigurator being used before it has been inited.
> Recommend synchronizing the getInstance() method.
