Quads and mergeGraph tests failing on Read with ClientProtocol Exception

[kkanthet]

String uri = "http://test.sem.quads/json-quads";
        String ntriple6 = "<http://example.org/s6> <http://example.com/mergeQuadP> <http://example.org/o2> <http://test.sem.quads/json-quads>.";
        File file = new File(datasource + "bug25348.json");
        FileHandle filehandle = new FileHandle();
        filehandle.set(file);
        gmWriter.write(uri, filehandle.withMimetype(RDFMimeTypes.RDFJSON));
        gmWriter.mergeGraphs(new StringHandle(ntriple6).withMimetype(RDFMimeTypes.NQUADS));
        FileHandle handle = gmWriter.read(uri, new FileHandle());

I am seeing the same Exception as in unitTest failure ..

Charles, any idea how the /triplestore/c60d18746c03e880.xml is sneaking in before the HTTP/1.1 start of the response?

[grechaw]

I've got a fix for this that will go into server code momentarily.
