I am currently on java 7 (I assume) yet I would like to upgrade my server to java 8 since a plugin doesn't work with java 7. Thanks in advance.
You won't be able to update java yourself so you're going to either have to find a different plugin to use or use an older version if they work with Java 8.
Do you know when hosthorde will update to new java version? Can they not include java 8 support in addition to 7?
