Parser does not show error on this invalid twig value

{% block content %}
    {{ path('foo'}) }}
{% endblock %}

When this invalid twig (extra right brace) is in your twig file, the NetBeans plugin does not show an error, but try and parse this in your browser using Symfony and/or Twig and it will tell you that there is Unclosed "(" in {} at line 2
