This leads to serious problems in the FileSystem cache and RPC > connection cache. We need to change the hashCode to be the identity hash code > of the Subject and change equals to use == between the Subjects. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
