so I have this specific warning, I use desugaring and this warning comes up. one of my third party dependencies use this Bifunction but since it can't be found, app crashes. What I've found is that maybe desugaring doesn't have Bifunction class so jackson can't convert it. I must say it only gets error on Android-API 23 marshmallow and works fine on Android-API >23 devices.
EDIT if I set desugaring to true or false this problem happens so I'm sure there is a problem with 3rd party libraries accessing Bifunction from java.util.function.
Code:
List<Message> list;
list = mapper.convertValue(mapList, new TypeReference<List<Message>>() {});
Warning comes when I try to build the application with Desugaring enabled:
Warning in C:\Users\Keivan Shirkoubian\.gradle\caches\modules-2\files-2.1\com.android.tools\desugar_jdk_libs\1.0.9\359e5e4f4784f23beb30ba454b41f6f992e58481\desugar_jdk_libs-1.0.9.jar:java/util/concurrent/ConcurrentHashMap.class:
Type `j$.$r8$wrapper$java$util$function$BiFunction$-V-WRP` was not found, it is required for default or static interface methods desugaring of `java.lang.Object java.util.concurrent.ConcurrentHashMap.compute(java.lang.Object, $-vivified-$.java.util.function.BiFunction)`
This is the crash log, it comes when I try to map my mapList to another list (List).

BiFunction from java.util.function package requires your project modules to be compatible with Java 8.
Try to upgrade your Gradle plugin to version 3.0.0 (or higher) and add Java 8 language feature support. Check the docs link:
If you have already did it, please share your Gradle configuration files.
