Hi Clause
So for a header I can define a Predicate, but for a property I can't?
Example with header: (that works?)
Predicate isSystemActive = header("isSystemActive").isEqualTo("true");
Example with property: (that doesn’t work?)
Predicate isSystemActive = exchangeProperty
("systemConfig.isActive").isEqualTo(true);
So later I can use:
choice().when(isSystemActive)

This is not simple language, but refers to a exchange property key with the
given name.
You need to use simple as predicate instead of exchangeProperty
