Here's how I download CSV files on the client side in my Java GWT application. Special thanks to Xavier John for his solution. It's been verified to work in FF 24.6.0, IE 11.0.20, and Chrome 45.0.2454.99 (64-bit). I hope this saves someone a bit of time:

public class ExportFile 
{

    private static final String CRLF = "\r\n";

    public static void exportAsCsv(String filename, List> data) 
    {
        StringBuilder sb = new StringBuilder();
        for(List row : data) 
        {
            for(int i=0; i0) sb.append(",");
                sb.append(row.get(i));
            }
            sb.append(CRLF);
        }

        generateCsv(filename, sb.toString());
    }

    private static native void generateCsv(String filename, String text)
    /*-{
        var blob = new Blob([text], { type: 'text/csv;charset=utf-8;' });

        if (navigator.msSaveBlob) // IE 10+
        { 
            navigator.msSaveBlob(blob, filename);
        } 
        else 
        {
            var link = document.createElement("a");
            if (link.download !== undefined) // feature detection
            { 
                // Browsers that support HTML5 download attribute
                var url = URL.createObjectURL(blob);
                link.setAttribute("href", url);
                link.setAttribute("download", filename);
                link.style.visibility = 'hidden';
                document.body.appendChild(link);
                link.click();
                document.body.removeChild(link);
            }
        }
    }-*/;
