[infinispan-issues] [JBoss JIRA] (ISPN-1359) SetExternalizer Cannot Properly Handle TreeSets Constructed With Comparator

SetExternalizer Cannot Properly Handle TreeSets Constructed With Comparator --------------------------------------------------------------------------- Key: ISPN-1359 URL: https://issues.jboss.org/browse/ISPN-1359 Project: Infinispan Issue Type: Bug Components: Marshalling Affects Versions: 5.0.0.FINAL Environment: OSX 10.7.1, System JDK Reporter: Ryan Scharer Assignee: Galder Zamarreño Priority: Minor Fix For: 5.2.0.Beta3, 5.2.0.Final TreeSets can be used to hold objects that don't implement Comparable, so long as you provide a Comparator during construction. The current implementation of SetExternalizer doesn't support this pattern... trying to deserialize a TreeSet that holds objects that don't implement Comparable results in a ClassCastException. This seriously reduces the flexibility of TreeSet. JBoss Cache doesn't have this limitation, presumably because it delegates to native Java serialization.
