KeyLengthCriterion not set in Decrypter

The method buildKeyLengthCriterion in org.opensaml.xmlsec.encryption.support.Decrypter has a bug that leaves the KeyLengthCriterion out from the criteria set being passed to the key encryption resolver ...

If the encryption method is set, null is returned. If it's not, we'll get an NPE.

if (!Strings.isNullOrEmpty(encAlgorithmURI)) {
  return null;
{{}}}

I'm currently building a key info provider for ECDH that will return the key agreement key, and for that I need both the JCA name and the key length. Others may not suffer from this bug ...
