Mockito 3.11.2 (?) fails with "can't load this type of class file"
See original GitHub issueBroken version: 3.11.2? Working versions: 3.10.0
Description
All was working OK with 3.8.0 and we upgraded to 3.11.2 but this presented the problem below. I have sequentially downgraded and it seems 3.10.0 doesn’t present me with any problems.
I have not been able to confidently isolate it to this version because I have also experienced #2316 and #2327 in the interim versions.
Our context is Android and a com.android.test instrumented test module. We are using org.mockito:mockito-core, plus org.mockito:mockito-android with the same version, and org.mockito.kotlin:mockito-kotlin:3.2.0.

Arghs, indeed. Fixed on master of Byte Buddy. Needed a fallback for the reflection dispatcher if dynamic class generation is not supported. Byte Buddy started to create an intermediate dispatcher in a separate class loader to avoid reflective calls to stem from its own context, otherwise method handle lookups might leak, for instance. For Android, this does of course break things.
Will be fixed in the next version.
Some more outfall in the Android ecosystem @raphw 😭
