I got an NPE when doing the following. Here is the class: public class Clazz { int x; int y; int z; } In an editor, select all 3 fields (the entire lines and including the whitespace after) and perform Pull-out refactoring from the context menu. I get the following stack Trace (selecting less and the exception will not occur): java.lang.reflect.InvocationTargetException at org.eclipse.jface.operation.ModalContext.run(ModalContext.java:421) at

The second exception trace, I think should be fixed after applying patch from 316809 This was the assert that checks whether an aspect's "getSource" ends with a "}". This check was only a safety check to see whether I got what I expected, before attempting to insert ITDs before that brace. While the check now fails, it looks like this is expected, and the source location is for the generated edits is still correct despite the assert failing there. So I have removed that assert. The first stack trace is an unrelated issue, I'll look into that.
Created attachment 175119 [details] Patch with a fix
Patch is applied and committed. Need to update push-in refactoring to use this.
