  /**
   * Resolve the given source and verify that the arguments in a specific method invocation were
   * correctly resolved.
   *
   * <p>The source is expected to be source for a compilation unit, the first declaration is
   * expected to be a class, the first member of which is expected to be a method with a block body,
   * and the first statement in the body is expected to be an expression statement whose expression
   * is a method invocation. It is the arguments to that method invocation that are tested. The
   * method invocation can contain errors.
   *
   * <p>The arguments were resolved correctly if the number of expressions in the list matches the
   * length of the array of indices and if, for each index in the array of indices, the parameter to
   * which the argument expression was resolved is the parameter in the invoked method's list of
   * parameters at that index. Arguments that should not be resolved to a parameter because of an
   * error can be denoted by including a negative index in the array of indices.
   *
   * @param source the source to be resolved
   * @param indices the array of indices used to associate arguments with parameters
   * @throws Exception if the source could not be resolved or if the structure of the source is not
   *     valid
