I think the answer is obvious:
1) FFI with Java is more theoretical then practical thing.
2) It is much easier to work with syntax tree as Haskell data type, then to
parse it from text into this data type first. Also in case you have to
parse not a single, but thousands of  sentences, then you have to code
special Haskell-call-Java-for-text-output synchronization logic. Or
Haskell-HTTP(REST) / JMS -Java Web_Service-Fun_Stuff.
Too much work to do a natural thing.

Of course I will have to go through all this fun staff once again. In fact
I already did this once - Web APP (Java GUI / GWT) + Haskell everything
else.
