Assertion error when determining monotonicity

Using JdbcExample.java as a starting point and changing the SQL query in the run method to:

select 2 * 2 * "empid" from "hr"."emps"

causes the following exception:

Exception in thread "main" java.lang.AssertionError: Internal error: invalid literal: 2 * 2
