-------------------------------
Summary: Add JDK compiler for runtime codegen
Key: SPARK-24498
URL: https://issues.apache.org/jira/browse/SPARK-24498
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 2.3.0
Reporter: Xiao Li
In some cases, JDK compiler can generate smaller bytecode and take less time in
compilation compared to Janino. However, in some cases, Janino is better. We
should support both for our runtime codegen. Janino will be still our default
runtime codegen compiler.
