So, I found my problem.
I initially thought that the problem lies in the question mark
Caused by: java.net.MalformedURLException: no protocol: META-INF/MyService-xmbean.xml?
and that it probably hide some unwanted characters so I tried pasting the text into notepad and such in order to see these characters and I didn't find anything.
I don't know what I did today that was different than before - but I found it.
