[jbossts-issues] [JBoss JIRA] (JBTM-2206) Use synchronized HashMaps

[Mark Little (JIRA)]

    [ https://issues.jboss.org/browse/JBTM-2206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12983646#comment-12983646 ] 

Mark Little commented on JBTM-2206:
-----------------------------------

I agree with Tom: public API changes need to be approached with caution. Of course we could deprecate APIs, but we'd need to support both for EAP 7 and then remove in EAP 8. The performance improvements for making this change in CheckedAction would need to be substantial to really make this worthwhile.

Note, this is precisely why I suggested when creating JBTM-2180 that we looked at each occurrence on a case by case basis. Sometimes we'll make the change. Sometimes we won't.

> Change usage of Hashtable into synchronized HashMap's instead.
