I noticed this as well after looking at the oAuth 1.0 sample code. If you enter your callback url without the protocol it will work. In your case just enter www.google.com. When you need the protocol you must url encode the querystring parameter.

https://fastlink.yodlee.com/appscenter/fastlinksb/linkAccount.fastlinksb.action?access_type=oauthdeeplink&displayMode=desktop&oauth_callback=http%3A%2F%2Fwww.google.com&oauth_consumer_key=XXXXXXXXXXXXXXX&oauth_nonce=6238157&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1407996476&oauth_token=11232e9a123111111d8a19175663ecd947&oauth_version=1.0&oauth_signature=4RbNDY9z1wC/vMV5neitQa7ZxQM=

While generating the signature you also need to include the URL and parameters. You can find libraries on JAVA for generating signature at Oauth JAVA

Also if you want to invoke the FastLink in a browser for testing then you can use steps from this article
