Sounds like a corrupt java installation. Try to reinstall java.

Edit: Might also be possible that the configuration of bungee has an error.

[TheDaChicken]

It was corrupt Java installation. Thanks!

How come the Java installation corrupt?

Usually that's not possible.
Clsoing this as the issue is fixed.
