Exception when using play-authenticate & memcached (play2.4)

[tuanvm]

Hello,

I used memcached with play-authenticate instead of default Ehcache, and i've got an exception when trying to login with Twitter provider.
Here are the exception log:

Do you have any idea about this issue? Login with other providers are still working fine, just with twitter provider, i got this issue when getting value from Cache.

Thanks.

@tuanvm Hi, thanks for using play2-memcached :)

Unfortunately, I can't figure out what is happening from the log.
Could you mind providing me an example app to reproduce the issue?

[tuanvm]

@mumoshu Thank you so much,
I created a sample app there https://github.com/tuanvm/play-authenticate-memcached-exception
It's just an exist example in play-authenticate repos, just change default ehcache to memcached.
Other providers as facebook still working fine, just exception with twitter only.
Thanks.
