title: Grails app fails to load on tomcat
body: <p>I have some spring beans defined using groovy dsl and "plugin-config". There are also libraries on classpath with regular spring xml contex.</p>
  
  <p>So I put to resources.groovy:</p>
  
  <pre><code>beans = {
      importBeans("classpath*:applicationContext.xml")
  }
  </code></pre>
  
  <p>When I run app using "grails run-app" command it works. But when I deploy the war to Tomcat 7 then it fails (points to <a href="https://github.com/daniel-lima/grails-plugin-config-plugin/blob/master/src/java/org/grails/plugin/config/AbstractConfigHelper.java" rel="nofollow">https://github.com/daniel-lima/grails-plugin-config-plugin/blob/master/src/java/org/grails/plugin/config/AbstractConfigHelper.java</a> - line 340):</p>
