Enable strict IRI parsing in query parser?

Is there an easy way to enable strict IRI parsing in the query parser?

For example the following user query is accepted by ARQ:

SELECT *
WHERE {
?subject rdfs:subClassOf <http:/google.com <http://google.com/
<http://google.com/>>> .

Note the incorrect URI, when put through the IRI validator at sparql.org
ARQ produces the following:

http:/google.com ==> http:/google.com
<http:/google.com> Code: 57/REQUIRED_COMPONENT_MISSING in HOST: A
component that is required by the scheme is missing.

Is there any way to get this behaviour from the query parser?
