Is it VTK 9.4 that broke or VS2022?
I have build the Java wrappers many times for VTK9.3 on VS2017 using the visual studio generators in CMake.
However the jar had to be built manually. VTK 9 and Java- vtk.jar not automatically generated. Also location of wrapper dlls - #19 by toddy
Has this step been automated now for Windows? It is causing the problem?
