I had to add an = sign for this to work with sketchPath() in layer in your code (subsketch_0 in my code):

final String[] switches = { ARGS_SKETCH_FOLDER + "=" + sketchPath(), "" };

Indeed, that was a very old example which I had forgotten to include an '=' character, which is required for the runSketch()'s switch/case block parser:

core/src/processing/core/PApplet.java

core/src/processing/core/PApplet.java

So this is the fixed line:
final String[] switches = { ARGS_SKETCH_FOLDER + '=' + sketchPath(), "" };
