bugfix: Try and fix issue with Base64 reflection

[tgodzik]

Based on https://github.com/dirs-dev/directories-jvm/blob/aa87fc1705fec69bc7f486dae6910306a50c221a/src/main/resources/META-INF/native-image/dev.dirs/reflect-config.json

Fixes #1718

Anyone willing to test it out on windows? Otherwise I can do that probably next week and run a new release.

I tried releasing it locally on Windows, but it seems a bottomless rabbit hole :/

Try is a simple instruction:
gu.cmd install native-image which should install native-image.cmd in the same folder, but it doesn't!

Spent an hour trying to google/fix that, but to no avail. I found native-image.exe, is that the same thing? It's in a totally different folder, but maybe it does work?

Then it started failing with not finding cl.exe, which needed Visual Studio being installed (!!!) and it still didn't help.

I think we will check this when the release runs :/

I honestly know nothing about what this is doing. Do you have any links or reference to what these are?

There is a bit more here: https://www.graalvm.org/22.1/reference-manual/native-image/Reflection/

But I ma kind of guessing here and copying from dev-dirs, which seems to have that setting

Ok, so this dirs-dev library tries to load java.util.Base64
by reflection here and to call getEncoder which probably returns a java.util.Base64$Encoder.

I wonder if we should also declare sun.misc.BASE64Encoder here. Probably not if we compile with Java 11 or greater.

I cannot test this change now but it seems perfectly legitimate to me.

I will try and build it on CI, might be possible to download it and test on windows.

That actually worked! 🎉

Alrighty, finally read through the link. Thanks! From what I can tell, yea this makes sense. LGTM
