Fixed #23 ClientConfig differs between appservers

[dmatej]

• test was successful if run against remote servers, but failed with embedded The cause was that the default server's private embedded payara provider is incompatible with the jerseys's
• solution: configure the jersey client to be independent on server settings/impl
• also done some cleanup and comments
• the test is faster now and has timeout set (hangouts were possible)
• no asserts lost now (try/catch/stacktrace replaced with collecting junit exceptions from each event processing and asserting that all assertions passed and no exception was thrown)

Looks good too. Small remark is that the final modifiers and this prefixes are mostly not really needed, but alas, it's a small thing ;)

[dmatej]

It depends, I often do some big refactorings in very ugly code and then they are helpful for readibility and even to avoid unwanted collisions. But I will respect rules in this repo next time (I see many "fightings" of tabs vs. spaces here too) ;)

[arjantijms]

Thanks! It's probably not "fightings", just mistakes ;) The rule should be spaces for this repo.
