A jdbc driver fails to open a web browser for single sign on

[mickpa]

This app just hangs when tried with a connection string that causes the jdbc driver to use single sign on, which involves opening a browser page.
Using native authentication works fine.

import jaydebeapi as jdb
conn = jdb.connect('com.ingres.jdbc.IngresDriver','jdbc:actian://my_dbserver:27839/db;encryption=on;UID=myuser;auth_type=cli;auth_server=authserver_url,google;', jars='iijdbc.jar')
cursor = conn.cursor()
cursor.execute("select count(*) from sample.l_airport")
result=cursor.fetchone()
print(result[0])
cursor.close()
conn.close()

kill -TERM python_pid
in another shell causes the below exception to show up after some time.
