Description

When the SPARQL server responds to a request with an error (e.g. 500 error), the Tomcat error response body provides detailed information about what went wrong. This response information is included in the underyling HttpException, but is being masked by faulty error handling code in org.apache.jena.sparql.engine.http.HttpQuery.

The rewrap() method should specify httpEx as the root cause of the exception, not httpEx.getCause(). This will ensure that the response body information is preserved.
