Using jjs to generate code with

function name(i) {
    var n = "";
    do {
        n = "abcdefghijklmnopqrstuvwxyz".charAt((i - 1) % 26) + n;
        i = Math.floor(i / 26);
    } while (i != 0);
    return n;
}

print("var x = {");
for (var i = 1; i < 26*26*26; i++) {
    print(" " + name(i) + ": " + i + ",");
}
print("};");
print("print(x.aaa);");

It's easy to create a test that yields

Exception in thread "main" java.lang.RuntimeException: Method code too large!

We should at least see if we can address this by splitting the literal initialization across methods. Also fails on Rhino, but okay on V8.
