### Steps to reproduce

1. Install Android Studio RC [ Android Studio Quali 3 RC 2 ]
2. Configure Flutter to use the bundled JDK from Android Studio RC.
flutter config --jdk-dir="/Applications/Android Studio RC.app/Contents/jbr/Contents/Home"
3. Create a Flutter module
flutter create -t module flutter_module
4. Navigate to the module[ cd flutter_module ]
5. Build the Android AAR. [ flutter build aar -v ]

### Expected results

flutter build aar completes successfully and generates the AAR artifacts.

### Actual results

The build fails during the javaDocDebugGeneration task with the following exception:
Caused by: java.lang.IllegalArgumentException: 25.0.2
at com.intellij.util.lang.JavaVersion.parse(...)

Research direction

Reproduce the failure with `flutter build aar -v` using Android Studio RC's bundled JDK 25, then compare it with the successful JDK 21 build. Start from the `javaDocDebugGeneration` task and the logged `JavaVersion.parse` exception; done means the AAR build completes successfully with JDK 25 and generates its artifacts.
