Typeface Activator did not compile CoffeeScript and auto-reloading stopped working

I use Scala to develop web applications in Play Framework.

Until yesterday, the development was going well, but Activator(sbt) did not compile CoffeeScript and auto-reloading did not work anymore.

I can think of it as a result of fiddling with the Java Control Panel in the system configuration, but it didn't work when I returned it to its original state.

plugins.sbt describes CoffeeScript.

If there is anyone who can consider the cause, please take care of it. We apologize for the lack of information. Thank you for reading.

The environment is

Mac OS X 10.10.1
Activator 1.2.10
Scala 2.11.2
Java 1.6.0_65
Play Framework 2.3.7

add...

The same symptom will appear in newly created projects in Activator orz

I don't have much information, so it's quite a guess, but

play is 2.3.5 and later, and the way it works has changed a lot (internal, divided into a module called run-support)
For 2.3.5 or later, Java 6 and Java 7 or later are separated
See this file and more specificallyhttps://github.com/playframework/playframework/blob/2.3.7/framework/src/run-support/src/main/scala/play/runsupport/PlayWatchService.scala

So for the time being, what I can think of is

Change Java version (try 7 or 8)
Change the version of play (try both play 2.3.4 and 2.3.5 and later)

and so on?
