[oe] How to get rxtx recipe to work

[Elvis Dowson]

Hi,
	What are the recommended settings for the following preferred  
providers for using the rxtx recipe?

I have set the following, are they okay?

PREFERRED_PROVIDER_virtual/javac-native = "openjdk-javac-native"
PREFERRED_PROVIDER_classpath = "classpath"
PREFERRED_PROVIDER_virtual/java-initial = "jamvm-initial"
PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"
