about pgjdbc ubenchmark

Dear Sir/Mandam:

I am a user of pgjdbc-9.4-1212 and I modified some source code of it.

Now.I want to check the performance of the modified code. I have noticed that there is a submodule named “ubenchmark”.
I guess it must be a performance test module, but I did not find any document of it.
Could you teach me how to use it or give me some document about it?
Or, is there any universal jdbc bench software that I can use to run performance test for pgjdbc?

Thanks a lot~
