constraint is a protected keyword with Optimica language extension

[lafrasu@…]

I get the following error when trying to load the Modelica Standard Library while also using the +g=Optimica option:

"[/usr/lib/omlibrary/Modelica 3.2.1/Mechanics/MultiBody/Examples/Constraints.mo:18:24-18:33:writable] Error: No viable alternative near token: Prismatic
Error: Failed to load package Modelica.Blocks (default) using MODELICAPATH /usr/lib/omlibrary:/home/lafras/.openmodelica/libraries/.

Without the Optimica extension the library loads. I suspect it's because a variable called constraint is created, however "constraint" is a keyword in Optimica.

So what is the problem?

setCommandLineOptions("+g=Modelica");
loadModel(Modelica);
setCommandLineOptions("+g=Optimica");
