Basically, you can't do that in pure Java - the compiler is a C++
binary, there is no Java version.
Still, working with the output of --descriptor_set_out is probably the
way to go here. If you have the .proto file ahead of time, you can
pregenerate the descriptor output at build time and store
You may be running into issues where the set of descriptors associated
