I think this is a consequence of the fix for bug 183211.  I am getting the following NPE when typing a static import statement into the editor:

!ENTRY org.eclipse.core.jobs 4 2 2008-03-19 13:40:04.008
!MESSAGE An internal error occurred during: "Requesting Java AST from selection".
!STACK 0
java.lang.NullPointerException
	at java.lang.String.<init>(String.java:176)
	at org.eclipse.jdt.core.dom.TypeBinding.getName(TypeBinding.java:621)

	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

To reproduce, create a project with the following two files:

  // p1/X.java:
  package p1;
  interface I { class A {} }
  class C { public static class A {} }
  public class X extends C implements I {}

  // p2/Y.java:
  package p2;

  class Y {}

Now, put the cursor in Y.java on the line before the class declaration, and attempt to type the following:

  import static p1.X.A;

The above NPE happens.  Closing the NPE error message immediately brings another error message to the front, and so forth, so there is no way to exit the editor except by killing the task in Task Manager.

This is a regression: in I20080305, all that would happen is that the static import statement would get a compile error, "type p1.X.A is not visible".
