Java 21 Support in Snyk Code

Improved

Starting May 1, 2025, Snyk Code will support Java 21 across all integrations, enabling full project scanning and improved accuracy.

  • Java 21: Support for new language features including record patterns and sealed classes.

  • Analysis Engine: Enhanced program analysis to align with Java 21 syntax and semantics.

  • Ruleset: Updated to cover security-relevant classes introduced in Java 21.

These updates will roll out as part of Snyk Code’s GA support for Java 21 and may result in changes to findings.
