Bug 12593 code assist inserts fully qualified type names (ignoring preferences)
20020328 package p; import java.util.List; public abstract class Test { public void foo() { List l= new List(){<CODE ASSIST HERE>} } } choose the 'addAll' method (any of the two) you get the fully qualified name for Collections (although my java editor/code assist preference says it should insert an import statement)
