You appear to be encountering this problem in hosted mode. If you are using a Sun (ahem I mean oracle) JVM you can use -XX:MaxPermSize to increase the perm gen space.
>From your stack trace you also seem to be using jrebel >(com.zeroturnaround.javarebel). This library may be introducing a bit of overhead in the perm gen space that helps you encounter this issue more easily. Hot deploy is fun though.
