Oh, thanks for your clarification and your help. Not sure how that should help in any way.

Testing with JDK 1.8.0_144 -> Working fine. Others having the same problem with the included Java, any other solution outside of staying at HTTP?

Same error:

That's the test configuration.

Yes, it works in every other non-Minecraft Java project. And I forgot to mention that it works when I use the Test Configuration of Forge.

Hey, my problem is with the SSL Engine of Forge: In every Init event (Pre, Init, Post) the HTTPS connection to my server fails with this exception: The code: As I already mentioned before, I tried the SSL Connection methods in every other initialization event too. The weird thing with that error is, that if I for example implement this method into a command of mine, it works flawlessly and without errors. When I switch to HTTP, everything works alright again.
