ActualRAM decompiled

README.md

As described by the author, ActualRAM is a small plugin that helps you find out how much RAM your server really needs.

I do not own this plugin, it was posted on Reddit (archived link) with only a jar file.

Some people were interested in the source code, so I decompiled it using Java Decompiler.
