NullPointerException TernOutlineContentProvider.java:182
I have recently started seeing these exceptions in the Error Log. They seem to be reported when I use File / Close All when in the Java or Node perspectives (but not reliably).
Problem: Problems occurred when invoking code from plug-in: "org.eclipse.ui.navigator".

I have exactly same exception.. it is being reported when I use package.json file in Node.js project.(open&close the file).
I think I upgraded to the latest Oxygen version of Eclipse and have not had this problem since.
