I try to start Play using command: play start [myapp] -Xmx512m -XX:MaxPermSize=256m, but it said , 

Unrecognized VM option `MaxPermSize`

-XX:MaxPermSize=256m should work. At least it works for me. But
because windows sucks perhaps you need to put some quotes
somewhere....

I don't think that the Xmx will change anything since it's a permGen problem.

Unfortunately, there's probably nothing you can do.

Some libraries keep references to the dynamically loaded classes, which is ends up by filling all the permgen space.

It's seems to be a well know issue with  CGLIB, which is used by hibernate.

the -XX:MaxPermSize should work though, you should report that bug.

Yes, need to put quotes around -XX:MaxPermSize=256m on Windows

You can add jvm.memory=-XX:PermSize=64m -XX:MaxPermSize=256m to
application.conf also

there is 2 tools u can use to "calibrate" the memory u need :  

jvisualvm.exe and jconsole.exe ( in  JDK /bin folder) . 

U will have 2 graphs with the memory used by your application  . 

it's odd error cause most of the time u have heap memory exception not perm gen .
