Qt 5.15.19 Fails to Build Android Application with OpenJDK 21

Description:-

Qt 5.15.19 fails to build an example application for Android using OpenJDK 21

Environment:

• Qt Version: 5.15.19

• Qt Creator Version: 14.0.2

• Operating System: Android 14

• JDK Version: OpenJDK 21 (Fails), OpenJDK 17 (Works)

Expected Behavior: The application should successfully build and deploy on an Android device using Qt Creator with OpenJDK 21.

Actual Behavior:

• Attempting to build the example application for Android using OpenJDK 21 results in a failure.

• Downgrading to OpenJDK 17 allows the application to build and deploy successfully on Android.

Steps to Reproduce:

1. Install Qt 5.15.19 and configure Qt Creator for Android development.
2. Set up OpenJDK 21 as the JDK in Qt Creator.
3. Open any example application and configure it for Android.
4. Attempt to build the application.
5. Observe the build failure with an error message.
6. Change JDK to OpenJDK 17 and rebuild.
7. Observe that the application builds and deploys successfully.

Workarounds Attempted:

• Reinstalling OpenJDK 21.

• Using different Gradle versions.

• Ensuring correct Android SDK and NDK versions.

• Switching to OpenJDK 17 (which resolved the issue).

Additional Notes:

• The issue is specifically observed with OpenJDK 21, while OpenJDK 17 works without problems.

• Qt documentation does not explicitly mention OpenJDK 21 incompatibility. https://doc.qt.io/qt-5/android-getting-started.html
