> When SimpleExpressionParser and SimplePredicateParser substitute init\-block keys in the expression string, shorter keys that are prefixes of longer ones could match first and corrupt the substitution. Sorting keys by descending length before substituting ensures longer \(more specific\) keys are always replaced first, preventing this prefix collision.
> Discovered during the work on CAMEL\-22894 \(simple language parser hardening\).
