When will Java 25 be available on Azure App Service for Windows OS?

Question

When will Java 25 be available on Azure App Service for Windows OS?

春木裕和 20

Hello. I'm currently building a system using Azure App Service. Since Java 21 will reach end of support two years after the system is released, I would prefer to develop with Java 25. I see that Java 25 is already available on Azure App Service for Linux OS, but do you know when it will be supported on the Windows version?

HI @春木裕和

Java 25 is not yet natively available as a selectable runtime on Azure App Service for Windows. The rollout started in late October 2025 and is happening gradually across regions.

If you require Java 25 right away, you can deploy your app using a custom Windows container with Microsoft’s OpenJDK 25, which has been available since September 2025.

Alternatively, Java 25 is already supported on App Service for Linux.

Once the rollout is complete, Java 25 will become natively selectable in the portal.

Could you please verify the current availability?

az webapp list-runtimes --os windows | findstr java

Hello @Praneeth Maddali ,

as you say and documentation indicates that JDK 25 is now available for Linux Web Apps. However, in my environment (region: West Europe) it does not appear to be available.

In the Azure Portal, JDK 25 is shown as a selectable option, but the configuration cannot be saved, which is confusing. Moreover, when listing runtimes with the Azure CLI, there is no trace of JDK 25:

az webapp list-runtimes --os linux | grep java JAVA:21-java21 JAVA:17-java17 JAVA:11-java11 JBOSSEAP:8.1.0.1-java21_byol JBOSSEAP:8.1.0.1-java17_byol JBOSSEAP:8-java21 JBOSSEAP:8-java17 JBOSSEAP:8-java11 JBOSSEAP:8-java21_byol JBOSSEAP:8-java17_byol JBOSSEAP:8-java11_byol JBOSSEAP:7-java17 JBOSSEAP:7-java11 JBOSSEAP:7-java8 JBOSSEAP:7-java17_byol JBOSSEAP:7-java11_byol JBOSSEAP:7-java8_byol TOMCAT:11.0-java21 TOMCAT:11.0-java17 TOMCAT:11.0-java11 TOMCAT:10.1-java21 TOMCAT:10.1-java17 TOMCAT:10.1-java11 TOMCAT:10.0-java17 TOMCAT:10.0-java11 TOMCAT:9.0-java21 TOMCAT:9.0-java17 TOMCAT:9.0-java11 TOMCAT:8.5-java11

Could you please confirm whether JDK 25 has been rolled out to West Europe and, if so, advise on the correct steps to enable it? If it has not yet been deployed to this region, please clarify the current status and whether the Portal display can be corrected to avoid misleading users.

Thank you.

HI @春木裕和

Native (built-in) Java 25 support is not yet available on Azure App Service for Windows.

According to official Microsoft documentation, only Java 8, 11, 17, and 21 are currently supported on Windows

reference : https://learn.microsoft.com/en-us/azure/app-service/language-support-policy?tabs=linux

The internal product group response you referenced (“This is pending deployment on Windows, but we don’t have a hard ETA for this yet”) is still the most recent update. There have been no public announcements or rollouts for Windows since the November 2025 discussion.

Java 25 became available on Linux App Service in late October 2025, although there were some temporary portal issues in certain regions during the rollout. However, Windows is still behind, and there is no confirmed timeline for its support. Kindly let us know if the above helps or you need further assistance on this issue.
