Failed to allocate closure when SELinux is enabled and non-root user is used

JNA fails to load a native library if SELinux is enabled and I run my code as a non-root user. I tested with Lazysodium for Java, but I don't think that this issue is specific to this particular library only.

Changing the SELinux mode to the permissive doesn't help and there is no record in /var/log/audit/audit.log.

If I run my code as root, the error won't occur. If I disable SELinux and I run my code as a non-root, the error won't occur either.

OS: Amazon Linux 2
System architecture: x86_64
Java: OpenJDK Runtime Environment (build 1.8.0_352-b08)
JNA version: 5.13.0

Steps to reproduce:

import com.goterl.lazysodium.SodiumJava;

public class JnaTest {

    public static void main(String[] args) {
        SodiumJava sodiumJava = new SodiumJava();
    }

}

Start by reproducing the failure on Amazon Linux 2 with SELinux enabled, as a non-root user, using JNA 5.13.0 and the provided Lazysodium example. Trace the failure from com.sun.jna.Native.registerMethod through Native.register and determine why closure allocation differs for this environment. Done means the native library loads successfully for the affected non-root configuration without weakening SELinux protections.
