> {{AbstractRelNode#getId}} can overflow into a negative value.
> This id is used by the {{implement}} method of several Enumerable operators
> ({{EnumerableBatchNestedLoopJoin}} and {{EnumerableMergeUnion}}) to guarantee
> a unique variable name in the dynamic code, e.g.:
> {code:java}
> final ParameterExpression corrArgList =
> Expressions.parameter(Modifier.FINAL,
> List.class, "corrList" + this.getId());
> {code}
> However, if the id is negative, this variable name will have a "-", causing a
> {{CompileException}}:
> {noformat}
> ...
> final org.apache.calcite.linq4j.Enumerable _inputEnumerable1 =
> org.apache.calcite.linq4j.EnumerableDefaults.correlateBatchJoin(org.apache.calcite.linq4j.JoinType.LEFT,

> java.util.List corrList-1794407755) {

> Caused by: java.util.concurrent.ExecutionException:
