My question may be too broad and probably the answer is a simple NO, but I have to ask. Is there any equivalent implementation of (Java 8) streams* in Java 7?

Nashorn under Java 7

I'm trying to get Oracle's Nashorn running under Java 7. I've cloned the repo and compiled the source. All I had to do to get it to compile was: Change jdk.internal.org.objectweb.asm.* to org.objectweb.asm.* Change one line that had Long.hashCode() static. Everything seems happy, and Java 7 sees Nashorn as a scripting engine; but when I try an
