Fixes #EVI-61576

Status

READY

Problem

Application fails on Java 25 with UnsupportedOperationException: getSubject is not supported during SASL authentication. Java 25 removed the deprecated Subject.getSubject() API that older Kafka clients relied on.

image
  • Upgraded Vert.x from 5.0.7 to 5.1.0, which includes Kafka clients 4.x with native Java 18+ support.
