Java Applet 100% CPU?

I’ve noticed that in the activity monitor (Mac) that the “Java Applet - mybooklive.local” takes up 100.1% CPU most of the time. Is this normal? I’m guessing that this is referring to the MBL’s separate CPU.

What page are you viewing in your browser when Java is doing that?

None. I use the gui in Safari, but even when that’s closed, I see the 100% cpu in activity monitor. In finder, it’s connected via afp.
