Remediate OWASP A10:2025 Mishandling of exceptional conditions

Recipe IDorg.openrewrite.java.security.Owasp2025A10Artifactorg.openrewrite.recipe:rewrite-java-security

OWASP A10:2025 covers improper error handling: swallowed exceptions, overly broad catch/throws declarations, sensitive information leaked through error messages and stack traces, missing null checks, missing switch defaults, and omitted break statements. This is a new category in 2025.
