["Joachim Müller (JIRA)" <je...@portals.apache.org>]

     [ https://issues.apache.org/jira/browse/JS2-931?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joachim Müller updated JS2-931:
-------------------------------

    Attachment: JS2-931-2.1.2-POSTRELEASE.patch.txt
                JS2-931-2.1.3-POSTRELEASE.patch.txt
                JS2-931.patch.txt

The attached patches address the problem. For the trunk, a java.util.concurrent.ConcurrentHashMap is used, the older versions must use Collections.synchronizedMap(..) with synchronizing the iterations :-(.

Please review.
