Why this query doens't return any result with jena and with protege does??

Presumably because Protege considers

x y "foo"^^xsd:string

to entail

x y "foo"

while Jena does not?

Try your query as

PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT ?equivalentClass
WHERE {
  ?equivalentClass owl:equivalentClass ?Class .
  ?Class rdfs:label "champinhons"^^xsd:string
}
