I tried compiling VTK 9.0 with Java wrappers in Visual Studio 9.0. With VTK 8.2, VS creates the project .class file and vtk.jar. With VTK 9.0, it does not; no class files nor vtk.jar. Therefore, building the INSTALL project in VS fails because it cannot find the vtk.jar.
I seriously hope that you do not give up on Java
