Migration [2.1.1] to [2.2.1] - NullPointerException - URLEncoder.encode(URLEncoder.java:188)

[Rimbaud Van Eetvelde]

Hello,

We are currently trying to upgrade to the new version of the play framework and we are currently having the following error. 

Is anyone having the same issue?

Thanks in advance,

Rimbaud

Are you setting a cookie or session property to null?

[Rimbaud Van Eetvelde]

Hello Ben,

Thanks to you we solved the problem; so never set a value to null in the session ;)

Thanks a lot ;)
