@ericbroda, thanks for the PR!! 😃

Can you fix the failing test and update the README?

The error in Travis CI:

  75 passing (4s)
  1 failing

  1) MBeanServerConnection #getAttribute:

@zuazo, I made the changes to the README and managed to fix the majority of test cases, however, there is one remaining error in test cases:

Uncaught Error: Error running instance method java.lang.IllegalArgumentException: argument type mismatch

I have spent a few days on this one item and I would like to humbly ask for your assistance in figuring out what I need to do to fix this one remaining test error. I will be happy to fix the remaining errors if you may be able to provide some guidance.

(Note: I know the code does actually work as I can run it successfully - it is just the test cases that seem to be causing the issue)

Merged in master manually. The fix in 4b89b12 and an improvement in 110d0ed.

Thanks for all your fantastic work @ericbroda. The PR you made is really hard to do. 😉

Released in 0.4.0.
