Generic types are omitted

[VahidN]

I'm trying to convert the latest java-parser to a .NET assembly using the following settings:

  <ItemGroup>
    <PackageReference Include="IKVM" Version="8.4.5" />
  </ItemGroup>

  <ItemGroup>
    <IkvmReference Include="javaparser-core-3.25.1.jar" />
  </ItemGroup>

It compiles fine and produces the output .dll file, but it converts the following code:

   default Optional<Position> getBegin() {
        return getRange().map(r -> r.begin);
    }

To this:

    [MethodImpl(MethodImplOptions.NoInlining)]
    [SpecialName]
    [LineNumberTable(42)]
    static Optional <default>getBegin(NodeWithRange P_0)
    {
        Optional result = P_0.getRange().map(new __<>Anon1());
        _ = null;
        return result;
    }

When I decompile the output .dll using the ILSpy, as you can see, its signature is just Optional and not the original Optional<Position>. Because its generics type info is omitted, it can't be used efficiently. Is there any solution for it?

Java doesn't consider generics at runtime. So the code we generate also doesn't.

We may need to re-visit this issue IF it is relevant to JavaParser in the JavaToCsharp project!

If we could coordinate, it is important!

Revisit what exactly? IKVM is a JVM implementation, not a language parser.
