Does not work with android.

[Vrakfall]

Hi,

Your library does not seem to work with android. As soon as I add memoization-core and memoization-caffeine to my gradle file, I get an Exception when trying to build the project. The gradle task that fails is transformClassesWithDexBuilderForDebug (for a debug build, ofc) (with multiDex enabled, btw). Here are the stacktrace:

I updated the first post as I had another issue with my build at the same time. Tho, there's still one linked to this library as illustrated by this last stack trace.

[sebhoss]

I'm not sure how to fix that or what is even causing that error. Recent versions of this lib now require Java 17 which is supported by the most recent version of Android. Maybe updating to newer versions of all involved pieces fixes that problem, but I cannot say for sure.

Help highly appreciated!
