I don't think the step from learning Java7 -> Java8 is comparable to Java6->Scala, but I really don't think that's the thing to be discussed*. People seem to be reluctant to debug Scala code in ISPN - and that's a productivity issue more than anything else. *Also as a java developer you have the general option of not learning Scala, but you don't really have the option of not keeping up with Java8.
