This is "the" error (see below). Unfortunately just be upgrading Janino to
3.0.8 the problem still is present.
the only 'unwrap' word in the generated code is here
...
public org.apache.calcite.linq4j.Enumerable bind(final
org.apache.calcite.DataContext root0) {
root = root0;
final org.apache.calcite.linq4j.Enumerable _inputEnumerable =
org.apache.calcite.linq4j.Linq4j.asEnumerable(((org.apache.calcite.test.ReflectiveSchemaTest.CatchallSchema)
((org.apache.calcite.adapter.java.ReflectiveSchema)
root.getRootSchema().getSubSchema("s").unwrap(org.apache.calcite.adapter.java.ReflectiveSchema.class)).getTarget()).nullables);
....
Does any ring bell ?
