SPARK-4044 [CORE] Thriftserver fails to start when JAVA_HOME points to JRE
instead of JDK
So, I think it would be a step too far to tell people they have to run
Spark with a JDK instead of a JRE. It's uncommon to put a JDK in production. So
this runtime script needs to cope with not having `jar` available.
I've added explicit checks to the two cases where it's used, but yes it's
only the second datanucleus case that matters.
At least there's an error message now, but, how about just adding the jars
anyway, if they're present, in this case?
