[jboss-jira] [JBoss JIRA] Commented: (JGRP-554) GroupRequest should use concurrency friendly JDK 5 collections

[Bela Ban (JIRA)]

    [ http://jira.jboss.com/jira/browse/JGRP-554?page=comments#action_12368850 ] 
            
Bela Ban commented on JGRP-554:
-------------------------------

Potential of deadlock between 

viewChange(): requests --> suspects

and

doExecute(): requests --> members --> suspects

Temp solution: moved acquisition of suspects in viewChange() out of requests scope, this works but is not elegant

> GroupRequest uses complex synchronization logic for collections used. This logic should be reviewed and upgraded to jdk5 collections if appropriate.
