p.s. I forgot to say, it should be reproducible with any documents, but I had inserted mine with the following function, which you can probably drop into the same package and run, +/- an import or two.

    public static void exampleA() {
        // Synthesize input content
        StringHandle doc1 = new StringHandle(
                "{\"number\": 1}").withFormat(Format.JSON);
        StringHandle doc2 = new StringHandle(
                "{\"number\": 2}").withFormat(Format.JSON);
        StringHandle doc3 = new StringHandle(
                "{\"number\": 3}").withFormat(Format.JSON);
        StringHandle doc4 = new StringHandle(
                "{\"number\": 4}").withFormat(Format.JSON);
        StringHandle doc5 = new StringHandle(
                "{\"number\": 5}").withFormat(Format.JSON);

        // Synthesize input metadata
        DocumentMetadataHandle defaultMetadata1 = 
                new DocumentMetadataHandle().withQuality(1);
        DocumentMetadataHandle defaultMetadata2 = 
                new DocumentMetadataHandle().withQuality(2);
        DocumentMetadataHandle docSpecificMetadata = 
                new DocumentMetadataHandle().withCollections("myCollection");

        // Create and build up the batch
        JSONDocumentManager jdm = client.newJSONDocumentManager();
        DocumentWriteSet batch = jdm.newWriteSet();

        // use system default metadata
        batch.add("doc1.json", doc1);       // system default metadata

        // using batch default metadata
        batch.addDefault(defaultMetadata1);  // XXX this needs a name change
        batch.add("doc2.json", doc2);       // batch default metadata
        batch.add("doc3.json", docSpecificMetadata, doc3); // XXX add back when bug fixed
        batch.add("doc4.json", doc4);       // batch default metadata

        // replace batch default metadata with new metadata
        batch.addDefault(defaultMetadata2); // XXX this needs a name change
        batch.add("doc5.json", doc5);       // batch default 

        // Execute the write operation
        jdm.write(batch);

        // Check the results
        // Doc1 should have the system default quality of 0
        System.out.println("doc1 quality: Expected=0, Actual=" + 
                jdm.readMetadata("doc1.json", new DocumentMetadataHandle()).getQuality()
                );
        // Doc2 should use the first batch default metadata, with quality 1
        System.out.println("doc2 quality: Expected=" +
                defaultMetadata1.getQuality() + ", Actual=" + 
                jdm.readMetadata("doc2.json", new DocumentMetadataHandle()).getQuality()
                );

        // Doc3 should have the system default document quality (0) because quality
        // was not included in the document-specific metadata. It should be in the
        // collection "myCollection", from the document-specific metadata.
        DocumentMetadataHandle doc3Metadata =  
                jdm.readMetadata("doc3.json", new DocumentMetadataHandle());
        System.out.println("doc3 quality: Expected=0, Actual=" + doc3Metadata.getQuality());
        System.out.print("doc3 collections: Expected: myCollection, Actual=");
        for (String collection : doc3Metadata.getCollections()) {
            System.out.print(collection + " ");
        }
        System.out.println();

        // Doc 4 should also use the 1st batch default metadata, with quality 1
        System.out.println("doc4 quality: Expected=" +
                defaultMetadata1.getQuality() + ", Actual=" + 
                jdm.readMetadata("doc4.json", new DocumentMetadataHandle()).getQuality()
                );
        // Doc5 should use the 2nd batch default metadata, with quality 2
        System.out.println("doc5 quality: Expected=" +

Gah, lunchtime food coma. Sorry. THIS REST request:

curl --anyauth --user admin:adm1n -H "Accept: multipart/mixed; boundary=BOUNDARY" -X GET http://localhost:8003/v1/documents?uri=doc1.json&uri=doc2.json&uri=doc3.json&category=quality

(The one in the original problem description was missing Accept headers).

Set status to Fix on behalf of bugtrack integration.

Should this still be assigned to Charles now that Sam is back? For some reason, I actually thought this had been fixed, though I haven't tried it to confirm.
