Servers won't start after Java 7 to 8 Upgrade

After upgrading to java 8, I can’t start any of my servers. I’m 99% sure it has to do with the java startup script because my servers do not generate any logs unlike with java 7. The problem is that I have no idea where the is located at. If any one of you would know and could help it would be really usefull! Thank you.

Why are you using a Java “startup script” rather than relying on MineOS to invoke Java for you?

I meant to say the server startup script is made to be executed under java 7 on the webui. I’m trying to change the startup command in MineOS so it uses java 8 instead.

MineOS relies on the Linux $PATH variable to decide which Java to use.

In most cases, if upgrading Java, that means the existing Java installation is removed and a new one is put in its place. Then, when invoking Java, whichever is found first is used. Here’s how you can tell which Java is used from the command line:

mc@mineos ~$ which java

If which returns a value, it is being used by MineOS. Check it’s the version you expect, too:

mc@mineos ~$ java -version
openjdk version "1.8.0_102"
OpenJDK Runtime Environment (build 1.8.0_102-8u102-b14.1-1~bpo8+1-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)

If you still can’t get servers to start, let us know:

a) what distro you’re using
b) how java WAS installed and generally what method did you use to upgrade it (downloaded it manually? apt-get?)
c) as your non-root user, can you start up the Minecraft instance yourself? (the paths are in the webui)
