How to use Java in ASP.NET Core 3.1?

I’m building a REST API with ASP.NET, which should ideally be able to use Java code. I’ve already managed to create a bridge between .NET and Java by using jni4net in a simple console application. This is absolutely necessary due the non-existing interoperability of .NET and Java.

Nevertheless I can’t create a bridge in my ASP.NET project by using jni4net. Apparently this is a common error due the fact that .NET core 2.1 or later versions do not support the methods shown below. I am refering to this question: "Error in the webapp while connecting with JVM using jni4net from C#".

MissingMethodException: Method not found: ‘System.Reflection.Emit.AssemblyBuilder System.AppDomain.DefineDynamicAssembly(System.Reflection.AssemblyName, System.Reflection.Emit.AssemblyBuilderAccess)’.

Note that I’m using .NET core 3.1 for my ASP.NET project and jni4net 0.8.8.0. Anyways I’m would change my .NET version if needed. My current implementation in Program.cs looks like this:

using net.sf.jni4net;

public class Program
{
    public static void Main(string[] args)
    {
        var setup = new BridgeSetup();
        setup.Verbose = true;
        Bridge.CreateJVM(setup); // Error is thrown here
    }
}

Does anybody know if there is a way to bypass this error OR how to use Java code in an ASP.NET project? I highly appreciate any help or suggestion, sheers!
