NullPointerException in org.hdiv.filter.ValidatorFilter

Just upgraded from 2.1.4 to 2.1.5. Getting this error on some requests during automated tests.

java.lang.NullPointerException

Hi,
have you also updated the hdiv-config and use Hdiv schema for configuration?

Please give us more information about your automated tests

They are Selenium tests so the webapp is fully deployed. This error comes up in about 1 out of every 1,000 requests with a very light user load. I'm guessing it will be much worse in production.

Hi,

can you give us an example of the web.xml and hdiv-config.xml files that you use?
What framework and version do you use?

web.xml fragment:

  <!-- HDIV -->
  <listener>
    <listener-class>org.hdiv.listener.InitListener</listener-class>
  </listener>

  <!-- HDIV Validator Filter -->
  <filter>
    <filter-name>ValidatorFilter</filter-name>
    <filter-class>org.hdiv.filter.ValidatorFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>ValidatorFilter</filter-name>
    <servlet-name>mvc</servlet-name>
  </filter-mapping>

applicationContext-hdiv.xml:

Reopen the issue if it continues in the last HDIV version.
Thanks
