Yahoo Finance Historical data downloader url is not working

I have used the following url to fetch the historical data from yahoo finance. From last 16th May, 2017 the url is not working.

http://real-chart.finance.yahoo.com/table.csv?s=AAL&a=04&b=01&c=2017&d=04&e=02&f=2017&g=d&ignore=.csv

Seems like they have changed the url and the new url is:

https://query1.finance.yahoo.com/v7/finance/download/AAL?period1=1494873000&period2=1494959400&interval=1d&events=history&crumb=l0aEtuOKocj

In the above changed URL has a session cookie which is crumb. Is there any idea how to get this cookie programmatically(in JAVA)?
