Hi Bernd, @1: I think the original intention of the code (before the PR) was to disallow the use of sslv2 or sslv3 for the tls handling code thus the hard-coding to tlsv1 as ssl is handled in another part of the class. But I agree, that we could remove the "else" and consequently all kind of hard-coded TLS config. In this way, we would trust in the jdk defaults.
@2: I think, that the aspect related to cyphers would be a separate issue / PR. I agree, that enabling all available cyphers (L602/L603) is not a good idea in general, but this code hasn't changed in the proposed PR :) wdyt?
