AndroidJavaProxy fails to proxy "java9.util.function.BiConsumer" class when special types are passed as arguments

AndroidJavaProxy fails to proxy "java9.util.function.BiConsumer" when special types - String, Boolean, etc. are passed as arguments

Reproduction steps:
1. Unzip file "bug-repro-project.zip", go to UnityProject folder and open the project inside
2. Build and run on Android device
3. Start logcat
4. Open the application and click on the color change buttons

Expected result: CSharpBiConsumer class with AndroidJavaProxy implemented from java9.util.function.BiConsumer accepts special types (String, Boolean, etc.) as of AndroidJavaObject result, AndroidJavaObject throwable parameters
Actual result: CSharpBiConsumer class with AndroidJavaProxy implemented from java9.util.function.BiConsumer fails to accept special types (String, Boolean, etc.) as of AndroidJavaObject result, AndroidJavaObject throwable java9.util.function.BiConsumer parameters

Reproducible with: 2019.4.30f1, 2020.3.19f1, 2021.1.23f1, 2021.2.0b13, 2022.1.0a11

Tested with:
VLNQA00332, Samsung Galaxy XCover4 (SM-G390F), Android 9, CPU: Exynos 7 Quad 7570, GPU: Mali-T720
VLNQA00004, Meizu MX5 (MX5), Android 5.0.1, CPU: MediaTek Helio X10 MT6795T, GPU: PowerVR Rogue G6200
VLNQA00099, Google Pixel XL (Pixel XL), Android 10, CPU: Snapdragon 821 MSM8996 Pro, GPU: Adreno (TM) 530

  1. Resolution Note (fix version 2022.1):

    Two things here:
    1. The repro project is invalid. It fails to find java9.util.function.BiConsumer and number '9' is removed from class name then it also fails to find other Java class it uses for testing.
    2. In any case it works as expected: AndroidJavaProxy by default searches for C# method with a matching signature. However, you can have a full control by overriding this method: https://docs.unity3d.com/2021.2/Documentation/ScriptReference/AndroidJavaProxy.Invoke.html
