> at our production ,when we have more than 20 agg expression, the compile
> time is high using the default janino. but when changed to jdk compiler,we
> gain fewer compile time than the janino one. Our product jdk version is 1.8.
> So the default one should be JDK , if user's jdk version is upper than 1.7.
> We should add another check condition to the ClassCompilerSelector.
