Hi Jonathan,
   Thanks for the idea, but I don't think so. In order to identify 
source code of different tests, I used a prefix(the test class's name) 
before _source.txt. e.g. 
ConstructorGetAnnotatedReturnTypeTest_source.txt. But none of the 
classes in the source code have such a name(they are all like 
TypeAnnoCls1). Besides, this is just for users' viewing. I think .txt 
files should be OK.

- Charlie
