Black Sun, Eclipse plugins.

The C# editor rocks - keep up the great work! I just tried upgrading to the 0.8.0p1 version using the latest greatest 3.2-M5 of eclipse.

The C# editor throws the following exception fairly frequently (at least every time you open a file)...

java.lang.NoSuchMethodError: org.eclipse.jdt.internal.ui.JavaPlugin.getWorkingCopyManager()Lorg/eclipse/jdt/ui/IWorkingCopyManager;

BTW I fixed this by just deleting the plugin...

sf.blacksun.eclipse.jdt_0.8.0

and the C# editor works fine again! :)
