How to add multivalued literals in solrj

How do I add multivalued fields when I'm using the Extracting Request Handler?

The documentation says

literal.<fieldname> Populates a field with the name supplied with the specified value for each document. The data can be multivalued if the field is multivalued.|

Using code looking roughly like this

HttpSolrClient solr = new HttpSolrClient.Builder("http://localhost:8983/solr/myindex").build();

solr.setParser(new XMLResponseParser());
ContentStreamUpdateRequest req = new ContentStreamUpdateRequest("/update/extract");

ContentStream contentStream = new ContentStreamBase.ByteArrayStream(bytes, xxx);

req.addContentStream(contentStream); 
req.setParam("literal.id", id);
...
req.setParam("literal.keywords", "[foo,bar]");  // Not working

req.setAction(req.getAction().COMMIT, true, true);

I have tried several ways of adding multiple values, but it comes out as a literal literal. What I've tried:

req.setParam("literal.keywords", "foo,bar");
---
req.setParam("literal.keywords", "[foo,bar]");
---
req.setParam("literal.keywords", "[\"foo\",\"bar\"]");
---
req.setParam("literal.keywords", "foo");
req.setParam("literal.keywords", "bar");

None of these results in a list in the index. Any ideas?

I found a solution:

ModifiableSolrParams params = new ModifiableSolrParams();
params.set("literal.keywords", "foo", "bar");
params.set("literal.id", resourceUrl);
...
req.setParams(params);

The ModifiableSolrParams can handle varargs, which setParam can't.
