What is MassiveCore?
MassiveCore is a Bukkit plugin that contains components the MassiveCraft developers use for developing other Bukkit plugins:
- ItemStack and Inventory serialization
- Commands
- Plugin Integration
- Data storage with JSON
- Disc IO
- … and much more …
Install
- Stop your server.
- Put MassiveCore.jar in your plugins folder.
- Start your server again.
Plugins Using MassiveCore
Internet Connections
MassiveCore sends anonymous usage statistics to bstats.org when your server starts and downloads the latest sponsor configuration file from massivecraft.com hourly. You can disable these internet connections by setting "metricsEnabled" and "sponsorEnabled" to false at the very bottom of the main configuration file.

You need to update to Java 7
Step 1. Update your Java SE Step 2. Update your Java JDK

Hey sir, I have encountered a problem, I'm kinda new to this server stuff, so please forgive if i'm not detailed enough.

Maybe, but have you made sure that you're running CraftBukkit/Spigot with Java 7?

Posted Jul 4, 2013I think mcore is going to be spitting out debug messages for a while... While mcore has updated their depency on Bukkit to include the latest update, vault and protocolLib, two plugins that mcore relies on, have dependcies that have not been updated to include the latest bukkit version, thus causing debug and breakings down the line...
Until some of the other plugin developers get on the ball, expect to see lots of debug messages and crashes everyone.

Posted Jul 4, 2013I noticed some errors within vault when I tried to compile vault from latest source involving how it links with CraftEconomy3. I don't know if that would affect the stability of mCore or not since it is built using vault as a source. Just a thought if any of the programmers/testers are working on a solution to the console spams.

Might be able to build you a custom build for 1.5.2 if you're not planning on bumping up to 1.6.1 Craftbukkit. Hopefully fix your errors. PM me if interested and attach a screenshot of the 6.4.1 errors you get with your 1.5.2 server.(Or raw paste data will do.)

Looks like an issue with Spigot or CraftBukkit. I'd report it to their respective error reporting sites.
Of course, each plugin in that error report may have to be corrected as well.

Posted Jul 4, 2013@MaximumBlock I think that would be NoCheatPlus being unable to pass the moving of a player to the server. I suggest updating NCP.

That only checks that the browser is running Java 7. You also have to set up the PATH variable to point to the correct Java 7 installation.
Alternatively, you could reference Java 7 directly in the startup script:
Of course, this path depends on where you installed Java 7.

Posted Jul 3, 2013I made sure I installed java 7 this morning before I posted the first time.
I even went to www.java.com/verify/ after to double check. See picture...
