      Solaris_JDK_1.2.1_02/bin/javac fails to compile the
      following class. The source looks ok to me:

      ---
      public class Test
      {
         private abstract class UserTreeNode
         {
            // remove "protected" here and it compiles
            protected class BIStates
            {
            }
            protected abstract String treeLabel();
         }

         private class Block_TreeNode
            extends UserTreeNode
         {
            // move this class def behind treeLabel() and it compiles
            protected class BlockBIStates extends BIStates
            {
            }
            protected String treeLabel()
            {
               return "";
            }
         }
      }
      --

      Javac reports:

      # Solaris_JDK_1.2.1_02/bin/javac Test.java
      Test.java:19: The method String treeLabel() declared in inner class Test. Block_TreeNode cannot override the method of the same signature declared in inner class Test. UserTreeNode. They must have the same return type.
