So, I wanted to create a Modded Multiplayer Server with Forge, and I went through all the required steps of multiple tutorials, but my server is only running in Vanilla. Whenever I try to launch forge-1.8.9-11.15.1.1902-1.8.9-universal, it crashes after a minute or so of running, and doesn't load the mods. Here is the crash report given:

The bug reports you've given are not the same issue that I'm having. I've having no problem with the freezing of the launcher. It is a Java and/or Forge issue which I am having and I am not sure how to solve it

Its the same fix, something is setting your RAM to -Xmx512, those instructions are for checking the most common one
