Correct my previous response: In DRILL-4778, JDK was faster in compilation but generated slower code. Janino was slower in compilation and generate faster code. Your JIRA did not mention how was the performance when running generated code. You may want to test this aspect as well.

But if we change the compiler to jdk，we gain lower compile process time. It seems jdk compiler is better .If that's tue,why not let jdk be the default one?
