How to use the GAECache with Play-1.1 ?
Takuya UESHIN
I mentioned that the GAECache might not be used by Play-1.1 with gae-module.
I tried using Cache without the scala-module but the problem was also occurred.
I believe the Cache should be initialized after Cache.forcedCacheImpl is set.
But now the initialization sequence is in the inverse order.
Therefore Play should be changed the initialize sequence,
or the gae-module should be changed to set the Cache.forcedCacheImpl
before Cache is initialized.
What do you think about that?
Or please let me know if I made mistakes.
Regards.

sequence has changed in play 1.1. I will try to fix it ASAP. Have you
reported the issue already?
Takuya UESHIN
I'm afraid I don't know how to report the issue.
Could you tell me the way?
Thanks.
