They have Ant tasks too. Seems one could have some tasks to build and store the 
signature files then use the check signatures task against pre-stored signature 
files to speed up the process. 

Just peeking at the source code it looks like it is just using strict 
signatures, so the issues with type expansion, such as with the BigDecimal issue 
I mentioned, should be accounted for I believe. The only cases it looks like it 
wouldn't work in place of good code coverage and tests in a target runtime are 
when classes are loaded by name, dynamic, versus strict source code. So, it 
isn't a complete solution in itself necessarily, but that depends on the logic 
being examined really:

Agree, it definitely looks promising.
