This is strange - there should be nothing browser specific about the
session.
Try to isolate the behavior by removing OAuth out of the equation. What
happens when you store a variable in session scope without the OAuth flow?
Does it change each time?

The whitelist only details JVM classes that are allowed. You can including
classes with your project as much as you like (as long as they don't depend
on the missing JVM classes) so to use Spring, you have to include the
spring jar file(s).

Hi Paul,
No problem being a noob :-) Yes, you're right, just add the relevant
libraries to your project and make sure they're included in the output,
which I think is default anyway (as opposed to libraries like lombok that
are just there at compile-time)

You would have to make an AJAX call passing the data to your app. From
there, your server side code (Java/Python/Go) can save the info into the
datastore or put it into session.
