Description of problem:
If a client put an object as byte[] into the cache, which is a self serialized class, the get will return the original class (if it is in the class path) instead of the byte[].
This is incompatible to ISPN5 (<JDG6.3) here the byte[] is returned in any case.

It seems this in unintentional due to the smart 'compatibility' mode at client side

Expected results:
return a byte array
