    Description

      While trying to build the qt hangman example, I noticed it fails with OpenJDK 21

      openjdk version "21.0.5-ea" 2024-10-15 

      Build command

      + mkdir -p /home/debci/hangman/qmake-build
      + cd /home/debci/hangman/qmake-build
      + /usr/lib/aarch64-linux-gnu/qt-android-6.7-arm64-v8a/bin/qmake  /tmp/autopkgtest-lxc.udgmlycc/downtmp/build.N0g/src/qtdoc/examples/demos/hangman/hangman.pro
      + make V=1 apk
