Migrate Java code from javax.* to jakarta.* namespace. Use only when the user explicitly asks for a javax to jakarta namespace or framework migration (for example to Tomcat 10+/11 or Jakarta EE), or when java-upgrade or spring-boot-4-migration delegates it. Finding javax imports alone does not authorize a migration.
