Joerg Schaible updated COLLECTIONS-266: --------------------------------------- Attachment: CC-266-final.patch I've added a new patch that combines all changes for the main source and the test case. > Issue with MultiKey when serialized/deserialized via RMI > -------------------------------------------------------- > > Key: COLLECTIONS-266 > URL: https://issues.apache.org/jira/browse/COLLECTIONS-266 > Project: Commons Collections > Issue Type: Bug > Components: KeyValue > Affects Versions: 3.2 > Reporter: Julien Buret > Priority: Minor > Fix For: 3.3 > > Attachments: CC-266-final.patch, COLLECTIONS-266.patch, > collections-testcase-266.diff, MultiKey.java, TestCollections266.java, > TestCollections266.java, TestCollections266.java > > > This is because the hash code of MultiKey is calculated only once. > So if the MultiKey is deserialized in an other jvm, and if one at least of > the subkeys defines its hash code with System.identityHashCode() (for example > all the enums does), then the hash code of the MultiKey is no longer valid, > and you can't retreive the key in your Map. > I fixed it by making the cached hash code field transient, and by > recalculating the hash code during deserialization. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
