Hi Mike,
The following solution doesn't solve the unchecked type cast problem.
But it respect PECS definition and accept a Map<String,
NSArray<String>> as parameter. Do you think it is reasonable?
public <V extends List<String> > WORequest treateRequest(String
method, String url, String anHTTPVersion, Map<String, ? super V>
someHeaders, NSData content, Map<String, Object> someInfo) {
...
someHeaders.put("foo", (V) Collections.singletonList("bar"));
...
}
Cheers,
Henrique

btw, this is what i was saying that the only typesafe way to do this
is to copy the original headers -- so you would do new
HashMap<String, List<String>>(originalHeaders) and then you'd have a
properly typesafe <String, List<String>> that you can happily insert
into whatever List<String> subtypes you want inside of
createRequest. But it takes a copy to do it, which kind of sucks.
