      Description

      Whenever I do a simple ASK query with SPARQL PATH like:
      """
      PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
      PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>

      ASK WHERE {<http://my.resource.org/someResource> a / rdfs:subClassOf * <http://my.resource.org/someClass> }
      """

      It works fine and returns TRUE if <http://my.resource.org/someClass> exists and is connected to someResource with type/subclass relationships. But if there is no connection between someResource and someClass I get indefinite
      "WARN : 113685 main com.bigdata.service.AbstractTransactionService.logTimeout(AbstractTransactionService.java:482): Waiting"

      instead of FALSE. There is no justification for such timeouts as I have less than a hundred triplets in my test database
