RSbuddy help please. error messages

If anyone has experience with running rsbuddy on linux (i am using Centos) can they please offer their advice to help me solve the following issue.

Everytime i run rsbuddy i can sign in, it saysing loading, then waiting for reflection. next thing that happens is the screen goes black and i see these errors. this started happening around 1 week ago.



any help would be appreciated as i have no idea what to do. thank you very much.

 

This happened on the last update, it happens to my vps and idk what to do!

 

try using a previous version of rsbuddy see if that works.
if not try updating all your java

 

this is how i install rsbuddy on my system:

wget vpsinfinity.com/rsbuddy/rsbuddy-install.sh
chmod +x rsbuddy-install.sh
sh rsbuddy-install.sh

how would i go about installing an older version?
