[ https://issues.jboss.org/browse/ISPN-5297?page=com.atlassian.jira.plugin.... ] Sanne Grinovero updated ISPN-5297: ---------------------------------- Description: Our current MapExternalizer doesn't support a TreeMap with a Comparator. Currently we ignore any user provided Comparator to the TreeMap. We can't just fix this as we will break backwards compatibility if a TreeMap serialized form was stored. The only method I can think of that would work consistently would be to properly implement VersionAwareMarshaller. was: Our current MapExternalizer doesn't support a TreeMap with a Compator.
