Lazysodium 5.1.1 doesn't load libsodium for Rocky Linux 8

[marseg]

Hi there,

I have an issue with starting my app that uses Lazysodium. And this issue is reproduces only on Rocky Linux OS but not other ones that I'd tried (ubuntu, macos):

Is this problem specific for this OS?
Or could you help me out somehow with this problem?

Thanks in advance,

Because Lazysodium bundles native binaries inside its resources folder, this exception is due to LazySodium failing to extract those binaries out of a nested JAR situation.

You could try to instantiate LazySodium by providing an absolute path to your own native binaries that you store somewhere. There is a constructor param to handle this.

Though I think this PR fixes the situation entirely terl/resource-loader#12
