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.

Subject: Which code compiler is better

The compile process is long when we have 20 sum or avg expression and the
compiler is janino. 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?
