org.rascalmpl.interpreter.control_exceptions.Throw
This class is for representing all run-time exceptions in Rascal. These exceptions can be caught by Rascal code. These exceptions can be thrown by either the Rascal interpreter - in case of a run-time error, or by Rascal code - using the throw statement, or by Java "built-in" methods, or by Java "embedded" methods.
Note that this class is final to emphasize the fact that different kinds of Rascal exceptions need to be modeled by different kind of exception values, not different kind of Java classes.

    catch (StaticError e) {
      if (forRascal) {
        throw new Throw(values.constructor(Exception_StaticError, values.string(e.getMessage()), e.getLocation()), (ISourceLocation) null, ctx.getStackTrace());
