----------------------------------
Summary: Update codeGen of metadataHandler in
JaninoRelMetadataProvider to include Class definition at begin of dynamic code.
Key: CALCITE-2196
URL: https://issues.apache.org/jira/browse/CALCITE-2196
Project: Calcite
Issue Type: Bug
Components: core
Reporter: jingzhang
Assignee: Julian Hyde
JaninoRelMetadataProvider uses IClassBodyEvaluator to compile generated code.
The generated classes can not be debugged in interactively using Idea using the
method referenced by http://janino-compiler.github.io/janino/ because generated
code only contains classBody.
If using ISimpleCompiler to compile complete compile unit instead of classBody,
we could step into the code.
