Burn Lewis commented on UIMA-1227:
----------------------------------

If we construct the getMeta reply on each service by serializing its binary 
typesystem, then comparing the string form of the typesystem should be 
equivalent to comparing the binary form.  And require no changes to the message 
formats.


> Help users debug binary CAS serialization problems

> In order to use binary CAS serialization for remote services, both client and 
> service must have identical type systems. If not the same, binary 
> deserialization is likely to throw exceptions. The service request handler 
> should catch these exceptions when using binary deserialization and add 
> message suggesting a likely cause of the problem: unequal type systems.
