??-May-2021 - 6.35.0-SNAPSHOT

The PMD team is pleased to announce PMD 6.35.0-SNAPSHOT.

This is a minor release.

New and noteworthy

Modified rules

  • The Java rule CompareObjectsWithEquals has now a new property typesThatCompareByReference. With that property, you can configure types, that should be whitelisted for comparison by reference. By default, java.lang.Enum and java.lang.Class are allowed, but you could add custom types here. Additionally comparisons against constants are allowed now. This makes the rule less noisy when two constants are compared. Constants are identified by looking for an all-caps identifier.
