 | Arbitrary file write during archive extraction ("Zip Slip") (`java/zipslip`) | Fewer false positive results | Results involving a sanitization step that converts a destination `Path` to a `File` are no longer reported. |
-| Double-checked locking is not thread-safe (`java/unsafe-double-checked-locking`) | Fewer false positive results and more true positive results | Results that use safe publication through a `final` field are no longer reported. Results that initialize immutable types like `String` incorrectly are now reported. |
 | Result of multiplication cast to wider type (`java/integer-multiplication-cast-to-long`) | Fewer results | Results involving conversions to `float` or `double` are no longer reported, as they were almost exclusively false positives. |
