      Description

      (See http://stackoverflow.com/questions/6386917/strange-exception-table-entry-produced-by-suns-javac)

      This program:

      class Test {
          public static void main(String[] args) {
              try {
                  throw new NullPointerException();
              } catch (NullPointerException npe) {
                  System.out.println("In catch");
              } finally {
                  System.out.println("In finally");
              }
          }
      }

      Produces the following bytecode for method main:

         0: new #2; // class NullPointerException
         3: dup
         4: invokespecial #3; // Method NullPointerException."<init>":()V
         7: athrow
         8: astore_1
         9: getstatic #4; // Field System.out
         12: ldc #5; // "In catch"
         14: invokevirtual #6; // Method PrintStream.println
         17: getstatic #4; // Field System.out
         20: ldc #7; // String In finally
         22: invokevirtual #6; // Method PrintStream.println
         25: goto 39
         28: astore_2
         29: getstatic #4; // Field System.out
         32: ldc #7; // "In finally"
         34: invokevirtual #6; // Method PrintStream.println
         37: aload_2
         38: athrow
         39: return


      With the following exception table:

        Exception table:
         from to target type
           0 8 8 Class NullPointerException
           0 17 28 any
          28 29 28 any

      The last entry in the exception table appears to be bogus.
