EDIT: After ticking on then off the use anakama java again it changed the java used, however it did not change any of the params meaning that the global params this guide tells you to set are overridden by the params that the launcher sends.
I see, well I wrote the guide in Feb 2015. So I am not claimed created I didn't deserve, this guide was written on stream by a user then went missing so I re-wrote it.
I fully agree the game should not shutter in anyway consider it was released in Feb 2012, 4 and a half years should be enough time to resolve this issue.
I wonder if a game dev or genuis at java would know how to disable their set parameters and use custom settings.
