CoreCLR test failure: `Java.InteropTests.JavaObjectTest.Dispose_Finalized`

[jonathanpeppers]

Android framework version

net10.0-android (Preview)

Affected platform version

.NET 10

Description

After merging #10354, a couple test runs are successful, but then one failed:

• https://devdiv.visualstudio.com/DevDiv/_build/results?buildId=12073441&view=ms.vss-test-web.build-test-results-tab&runId=136520953&resultId=100449&paneView=debug

Mono.Android.NET_Tests, Java.InteropTests.JavaObjectTest.Dispose_Finalized / Release

System.AggregateException : AggregateException_ctor_DefaultMessage (  Expected: True
But was:  False
)
----> NUnit.Framework.AssertionException :   Expected: True
But was:  False

Test source:

• https://github.com/dotnet/java-interop/blob/f361b9945f3a94e22f299e2b705852f4d28ec845/tests/Java.Interop-Tests/Java.Interop/JavaObjectTest.cs#L106-L124

So, I suspect the test is flaky and fails some percentage of the time.

We should check out if this is a bug, or if the test can be improved.

Steps to Reproduce

Run tests\Mono.Android-Tests\Mono.Android-Tests\Mono.Android.NET-Tests.csproj several times

Did you find any workaround?

Run it again, it passes sometimes.

@jonathanpeppers I was not able to reproduce the test failure. The test is passing for me in both Debug and Release configuration with CoreCLR 🤔

[jonathanpeppers]

It could be a rare/race condition type thing.

I was looking and for some reason our CI is still API 29:

android/build-tools/scripts/TestApks.targets

Line 22 in 855887f

<TestAvdApiLevel Condition=" '$(TestAvdApiLevel)' == '' ">29</TestAvdApiLevel>

So, I can try updating this in the meantime.

This hasn't happened again yet. Will reopen if it does.
