you tried to compile with Java 11 and tried to run it with Java 8.

 

45 = Java 1.1
46 = Java 1.2
47 = Java 1.3
48 = Java 1.4
49 = Java 5
50 = Java 6
51 = Java 7
52 = Java 8
53 = Java 9
54 = Java 10
55 = Java 11
56 = Java 12
57 = Java 13

Something going wrong with you java settings. Probably the path is wrong or you compile with the wrong java version.

[TGSLineage2]

It could be that you have more than one java version installed and it is currently running with a different version than the one you need.

External MMOCore project is deleted on public sources since 3 months, not sure why you speak about it.

 

MMOCore is basically the network core, queuing/sending packets and it was merged with sources since a very long time, on commons package.

 

It was left here because SweeTs didn't know / didn't have the power to remove a project, and I wasn't administrating public sources because of inner lazyness.

Hi, I also have a question about Java. I have a server on java 11 and a friend on java 8. we want both on the same machine. Can these servers work together? and how?

[Seamless]

you cant run 2 instances in one machine. Only if youuse virtual box 

[SweeTs]

Compile both packs using java 11 and enjoy. There is no reason to use java 8 while you can 11 easily.
