JAX WHITEPAPER 2022

AKTUELLE JAVA-ARCHITEKTURMODELLE

Die beliebte Programmiersprache Java hat mit dem JDK 17 wieder eine LTS-Version erhalten. Was die aktuelle Version umfasst und was sie Neues bringt, erfahren Sie im JAX-Whitepaper 2022.

Angesichts der gravierenden Sicherheitslücken der letzten Monate, wie zum Beispiel der log4j-Vorfall oder der Angriff auf SolarWinds geht das Whitepaper außerdem der Frage nach, wie sich der Security-Prozess in der Softwareentwicklung verbessern lässt.
