Play 2 Scala run后错误

Play 2 Scala run后异常
play -> run 报错:

play.api.UnexpectedException: Unexpected exception[ObjectExistsException: Cache play already exists]

Caused by: net.sf.ehcache.ObjectExistsException: Cache play already exists

Application.conf 文件中加上一行ehcacheplugin=disabled,可以解决。
具体不知道什么原因。
