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.
