The code in `Integer.decode()` and `Long.decode()` might allocate two instances
of Integer/Long for the negative values less than -127:
Integer result;
result = Integer.valueOf(nm.substring(index), radix);
result = negative ? Integer.valueOf(-result.intValue()) : result;

For security reasons, the getURLClassPath() method should return a copy of
ucp, not the reference to ucp, to prevent the caller from modifying the
