Subject Re: CacheEntry serialization failure

The most straightforward solution which comes to my mind - *do not ever use
BinaryMarshaller by default*. Always fallback to OptimizedMarshaller unless
user explicitly asked us to use binary format (e.g. through package
wildcards).

BTW, we already do this for Externalizable and readObject/writeObject.
