SecureXmlDecoder cannot deserialize enums created in Java 6
This affects the PublisherData table and possibly CAData.
For PublisherData it is possible to workaround by deleting the publisher from database and re-creating it (and selecting it again in profiles etc.)
It is not yet known if there is an upgrade path that affects CAData (i.e. if there is an EJBCA version that had enums in CAData and also supported Java 6). For CAData it could be more difficult to work around.
The encoding is slightly different in Java 6 compared to later versions (XmlEnc$TestEnum is the enum class, BBBB is the enum value)
