      Description

      FULL PRODUCT VERSION :
      java version "1.5.0_04"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
      Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing)


      ADDITIONAL OS VERSION INFORMATION :

      A DESCRIPTION OF THE PROBLEM :
      The following program :

      class Foo {
          class C<T> { public static Class classOfT = T.getClass();}
          class D<T> { }
          class E<T> extends D< T.classOfT> { }
      }

      When compiled with "javac Foo.java" always yields the following error:

      java.lang.NullPointerException

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Create a file Foo.java which contents are:
      class Foo {
          class C<T> { public static Class classOfT = T.getClass();}
          class D<T> { }
          class E<T> extends D< T.classOfT> { }
      }
      Then try to compile the file with the command "javac Foo.java".

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      I was expecting the byte code class files "Foo.class" "Foo$C.class" "Foo$D.class" "Foo$E.class" to be created.
      ACTUAL -
      Instread I get this message:
      An exception has occurred in the compiler (1.5.0_04). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade forduplicates. Include your program and the following diagnostic in your report. Thank you.
