In Sesame the implementation is very ugly.
We first have to assume it is a tuple query, parse it, then parse it as a boolean query
See Issue SES-1054
We are waiting for a fix for this problem.
If you can't wait for the fix, it would be better to write
a parser directly or a mapper from Jena's implementation. Parsing sparql or json queries can't be
that difficult.
