Java executable check succeeds despite no java on PATH

Details

    Description

      The check -z $JAVA on line 102 of bin/cassandra currently always succeeds if JAVA_HOME is not set since in this case JAVA gets set directly to 'java'. The error message "Unable to find java executable. Check JAVA_HOME and PATH environment variables." will never be echoed on a PATH misconfiguration. If java isn't on the PATH the failure will instead occur on line 95 of cassandra-env.sh at the java version check.

      It would be better to check consistently for the java executable in one place in bin/cassandra. Also we don't want users to mistakenly think they have a java version problem when they in fact have a PATH problem.

      See proposed patch.
