Working !!! Thanks a lot ! Was struggling with it for 3 days. Any way to thanks you on this forum ?

Well.. dude you're right. I hate myself for not noticing it. Was so focused on the error, being sure that was my computer bad. Thanks a lot, changed the Java of the Server, trying it and come back to you to give some news. Thanks a lot.

I'm sure i'm running it with Java 8, also checked my Java version... don't seem to use Java 9 or Higher.
