prepare() server internal error when using TTL

** <b>AWS Update:</b> Keyspaces now supports TTL: https://aws.amazon.com/blogs/database/announcing-amazon-keyspaces-time-to-live-ttl-general-availability/ **

I am seeing an internal error returrned from key space when I try to prepare the following statement.

		createAccessToken = getSession().prepare(  
				"INSERT INTO access_tokens" + "(atokenid, atoken, useruuid, auth, clientid, expiration, time, code, version)"  
						+ "VALUES (?,?,?,?,?, ?,?,?,?) IF NOT EXISTS USING TTL ?;");  

The issue appears to be with the USING TTL ? since the following prepare doesn't exhibit the issue.
createAccessToken = getSession().prepare(
"INSERT INTO access_tokens" + "(atokenid, useruuid, atoken, auth, clientid, code, expiration, time, version)"
+ "VALUES (?,?,?,?,?, ?,?,?,?) USING TTL 200;");
Anybody know of a work around that doesn't have me hard code the ttl?
