 /**
  * This class represents the GCTR function defined in NIST 800-38D
- * under section 6.5. It needs to be constructed w/ an initialized
- * cipher object, and initial counter block(ICB). Given an input X
- * of arbitrary length, it processes and returns an output which has
- * the same length as X. The invariants of this class are:
- *
- * (1) The length of intialCounterBlk (and also of its clones, e.g.,
- * fields counter and counterSave) is equal to AES_BLOCK_SIZE.
- *
- * (2) After construction, the field counter never becomes null, it
- * always contains a byte array of length AES_BLOCK_SIZE.
+ * under section 6.5.  With a given cipher object and initial counter
+ * block, a counter mode operation is performed.  Blocksize is limited
+ * to 16 bytes.
  *
  * If any invariant is broken, failures can occur because the
  * AESCrypt.encryptBlock method can be intrinsified on the HotSpot VM
  * (see JDK-8067648 for details).
  *
+ * The counter mode operations can be intrinsified and parallelized
+ * by using CounterMode.implCrypt() if HotSpot VM supports it on the
+ * architecture.
+ *
  * <p>This function is used in the implementation of GCM mode.
  *
  * @since 1.8
