Thanks.

You are right, I was mistaken. I will have to make sure WebSocket test cases
perform their cleanup correctly. Looks like it's not the only test file that
has this issue.

Try-with-resources might be okay and self-contained, true. However, for my
liking it's a bit messy for this purpose. It's a duplication in every method and
eats up one full indentation block. @AfterMethod [1] seems to be the right thing
to do.
