Exception after startup

[grimes2]

I want to report an exception after startup of 2.11.1:
Exception in thread "main" java.lang.NoSuchMethodError: localcopy.LocalCopySidePaneComponent.setContent(Ljava/awt/Component;)V
at localcopy.LocalCopySidePaneComponent.(LocalCopyPane.java:219)
at localcopy.LocalCopyPane.getSidePaneComponent(LocalCopyPane.java:578)

This is because we worked on the internals of JabRef. In the future, we will drop plugin support. See #152.

A longer discussion is made at lehner/LocalCopy#7.

So, please disable the LocalCopy plugin and wait for the 3.0 release to happen switch to the latest release.
