Fix strcmp treating null and empty strings as equal#1069
Merged
Conversation
Previously, strcmp could return equality when comparing a null value with an empty string. This happened because rtrim(null) returned an empty string, causing null and "" to be treated as equivalent during comparison. This change preserves the semantic difference between null and empty strings by handling null values explicitly and delegating comparison to Comparator.nullsFirst after trimming. Behavior: - null is considered less than any non-null String - empty strings are not equal to null - trailing whitespace is ignored during comparison Issue: 207440
