Redundant array copy in UnsharedNameTable

The UnsharedNameTable.fromUtf8 method does this:
         byte[] bytes = new byte[len];
         System.arraycopy(cs, start, bytes, 0, len);
         n = new NameImpl(this, bytes, index++);
         System.arraycopy(cs, start, n.bytes, 0, len);

The 2nd arraycopy is unnecessary.
