SoftAssertions java.lang.IllegalArgumentException: Could not create type

[tommyalatalo]

I keep getting an IllegalArgumentException when trying to use SoftAssertions, I've tried using several of the libraries provided:

org.assertj.core.api.JUnitJupiterSoftAssertions
org.assertj.core.api.SoftAssertions
org.assertj.core.api.Java6SoftAssertions,
org.assertj.core.api.Java6UnitSoftAssertions

no matter of how I state the assertions in the code (using lambda, JUnit @rule, JUnit5 @RegisterExtension etc. I keep getting the attached error.

I'm trying to do this on Android, running 8.0 and JUnit 5 with the dependency set in my gradle build to;
androidTestImplementation "org.assertj:assertj-core:3.11.1"

My test class in short

import static org.assertj.core.api.Assertions.assertThat;

public class tester {
@RegisterExtension
    public final JUnitJupiterSoftAssertions softly = new JUnitJupiterSoftAssertions();

Test
    public void test1() {
        softly.assertThat(true).as("Soft assertion is working: ").isTrue();
}

Above code is of course truncated, but all my efforts have resulted in the below error.
I'm wondering if I'm doing something wrong as there are no open issues for this that I can find.

Hi,

for SoftAssertions AssertJ uses https://github.com/raphw/byte-buddy

If I understand http://bytebuddy.net/#/tutorial ("Loading classes in Android applications" section) correctly, (normal) Byte Buddy does not work on Android.

Sorry!

Then this should be clear in the documentation, I spent hours on this yesterday and there was no mention of incompatibility with Android, on the contrary there is a section on the AssertJ site on how it works with Android: http://joel-costigliola.github.io/assertj/assertj-core.html#android
You should either update the section on android and put in a mention for SoftAssertions or hopefully fix the problem, preferrably the latter because soft assertions seem like a great tool!

[joel-costigliola]

Fair enough, this should clear in the doc.

[joel-costigliola]

done. http://joel-costigliola.github.io/assertj/assertj-core.html#android

There is a version of ByteBuddy for Android: byte-buddy-android. Couldn't it be used instead of regular bytebuddy for AssertJ? Lack of SoftAssertions is really painful for Android. I have to wrap normal assertions, catch errors and then at the end present user results. Please check if Android version of ByteBuddy can be applied for AssertJ.
