Solved Plugin only works on a local server?

Hi. I am testing my new plugin, and it works perfectly fine on a local server hosted by my laptop, but then when I tried uploading it to my Ubuntu server, I kept on getting this error, when I walk through a portal:

Code:

[10:16:21 WARN]: [PortalPlugin] Task #3 for PortalPlugin v2.0 generated an exception

As far as I can tell, it's running the right version of Bukkit, and I don't know what's wrong. Can anyone see any problems?

 

@TheSporech you should not have the same version of java on your Ubuntu server and on your pc. That of your Ubuntu server should probably be lower. Which version of your java have you on your pc?

 

@0verFull
I'm 99% sure that would return a Major.Minor mismatch.

But check anyway.

 

@CraftCreeper6 I'm sure too

 

@TheSporech by the looks of it, your plugin starts up so it's not the java-version, can we see your PlayerListener class?

And your task.

 

java.lang.ClassCastException: org.bukkit.craftbukkit.v1_9_R1.entity.CraftRabbit cannot be cast to org.bukkit.entity.HumanEntity
What could be the problem...

 

I have no idea where that comes from... I never cast CraftRabbit to a HumanEntity...

Hope this helps
Sorry for posting the classes in their entirity. I have no idea what's causing it, so I don't know how much of them is relevant.

 

I mean geez.

 

Ik it doesn't work, but that's a different issue

 

@TheSporech

I showed you exactly what was generating the stack trace you saw. It will generate that same stack trace for any falling entity.

 

Okay, I'll improve this part, but why does it work on my local server but not my ubuntu one? More importantly the second error.

 

@TheSporech
Well according to the javadoc for Map (Java 7) and Map (Java 8) the method you mean is a default method introduced in Java 8. On your local server you have 8 installed, on the remote not. Stop using that method.

 

Ok thanks! I'll see what I can do.

 

..i had this same error hes not using java jdk hes using environmental version... Use jdk
