The minimum Scala version required in order to use the Scala Openspaces extension is 2.10
Overview
Several extensions to OpenSpaces API have been introduced to provide a more natural way of combining Scala with XAP.
General Setup
Assuming there is a scala installation under $SCALA_HOME, the jars under $SCALA_HOME/lib should be copied to $GS_HOME/lib/platform/scala/lib. Another options is to change setenv.{bat,sh} so that $SCALA_JARS points to $SCALA_HOME/lib.
