title: Spring boot ignores "ignoreUnresolvablePlaceholders" = true
body: <p>I'm having a problem with my Spring Boot application ignoring my <em>ignoreUnresolvablePlaceHolders</em> set to true in my config.xml file.</p>
  
  <p>I have these options explicitly set:</p>
  
  <pre><code>&lt;property name="ignoreUnresolvablePlaceholders" value="true" /&gt;
  &lt;!-- &lt;property name="localOverride" value="false" /&gt; --&gt;
  &lt;property name="ignoreResourceNotFound" value="true" /&gt;
  </code></pre>
  
  <p>It works fine in a Junit but when I run my app as a Spring Boot it throws a <em>Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder</em> on startup.</p>
  
  <p>Everything started to fail when I added Spring Profiles like this:</p>
  
  <pre><code>&lt;beans profile="default,dev"&gt;
  </code></pre>
  
  <p>Any help would be very much appreciated...</p>
