In changeset 347 to the jdk8tl langtools repository, some whitespace was removed from println()s. In the case of visitLocalVariableTable() and visitLocalVariableTypeTable(), the same changes were not applied to both methods. The former was not switched to use String.format() and the format string was not changed to start with %5d (instead of %8d).

The latest 7u and 8 builds exhibit the same behavior:
      LocalVariableTable:
        Start Length Slot Name Signature
             150 5 6 e Ljava/lang/Exception;
               0 156 0 this LC4;
               0 156 1 a [Ljava/lang/String;
              52 104 2 f0 Ljava/io/File;
              63 93 3 f1 Ljava/io/File;
              66 90 4 cf0 Lcom/sun/tools/classfile/ClassFile;
              69 87 5 cf1 Lcom/sun/tools/classfile/ClassFile;

Running javap -v -p on any class file that has a LocalVariableTable attribute shows the columns are misaligned.
