Description

When running the SWTBot test suite it get stuck at some point.

Evidence:

• Below is one thread of the thread dump.
• The default time limit of a connection in Studio is 0 by default, which in the API is converterted to Long.MAX_VALUE ms. So the ResponseFuture.get() blocks practically forever.
• This only happens when running the whole test suite, but then it is reproducable. When running only parts of the suite it runs through.

First steps:

• I'll try change the default time limit to 30 seconds.
