[jira] [Commented] (OPENJPA-2245) NotSerializableException when
using a remote QueryCache and the Criteria API
[ https://issues.apache.org/jira/browse/OPENJPA-2245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13427279#comment-13427279 ]
Rick Curtis commented on OPENJPA-2245:
--------------------------------------
Rather than making CriteriaQueryImpl and all objects it references serializable, it is much simpler to hold onto the stringified version(SQL) of the CriteriaQuery in the QueryKey.
