Comment 2 Gustavo Fernandes 2016-11-02 13:31:01 UTC

JDG 6.1 server, in order to write to the cache store, wraps the cache value into a o.i.server.core.CacheValue object that contains the byte[] and a version number for the entry. The externalizer for CacheValue has id 1100.

JDG 6.6 does not use CacheValue anymore so when reading something persisted with JDG 6.1 server cannot unmarshall CacheValue objects
