[jira] [Commented] (OPENJPA-1646) DataCacheManager initialization still isn't thread safe.

    [ https://issues.apache.org/jira/browse/OPENJPA-1646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15312128#comment-15312128 ] 

Alexander Riss commented on OPENJPA-1646:
-----------------------------------------

there still is an issue with the initialization when done concurrently:

The dataCacheManager is constructed AND published here:
https://github.com/apache/openjpa/blob/ee299cc0bd0942ef8da2156c36e342a443bb46a0/openjpa-kernel/src/main/java/org/apache/openjpa/conf/OpenJPAConfigurationImpl.java#L685

this means that it can then be read in line 683 before initialize is called
