New serialization method from uima 2.4.2 broke CAS visualization in cse-gui

[ziy]

Due to the new serialization method, the cas blob is no longer accessible by non-UIMA SDK based program, e.g. the new CSE GUI, which used to gunzip the blob and treat it as an XMI string and do the parsing. I don't know if the new 2.4.2 still has the old serialization method available in the package, but what I might suggest for now is to have both serialization methods available for uima-ecd. A common use example is that we use the new serialization method for intermediate data persistence, and directly store the compressed XMI string generated from the last cas in the pipeline. We can have two different "persistence-provider"s or "phase"s, and users are responsible to use the right one for each phase.

I agree, we can follow your suggestion, let me fix that tonight.

Thank, @elmer-garduno . Do we also need an additional field in the cas_str table to indicate what serialization method is used, maybe?

I think the deserializer has some heuristics to achieve that, let me find
out later.

Some header trick maybe?
