Maybe an answer here : GWT Issue 4552

If you neglect to add an import for an anonymous class like so:

FocusPanel dropdown = new FocusPanel();
dropdown.addClickHandler(new BloggiDiBlook() {});

where class BloggiDiBlook is neither in the enclosing class's package, nor imported in the enclosing class's .java file. There ought to be an appropriate "Class not found" or similar compiler error. Instead, the JDT Compiler throws the following NullPointerException
