title: Upgrading to commons-collections4 throws NoClassDefFoundError
body: <p>I am upgrading the libraries in my pom of an older project and I have encountered a problem while upgrading from org.apache.commons commons-collections 3.2.1 to org.apache.commons commons-collections4 4.0. I know that it is not backwards compatible but I thought I made the necessary adjustments.The old jar is not in the project repository anymore.</p>
  
  <p>It compiles fine but when I run the tests I always get this exception:</p>
  
  <pre><code>Caused by: java.lang.NoClassDefFoundError: org/apache/commons/collections/map/LRUMap
      at org.hibernate.util.SimpleMRUCache.init(SimpleMRUCache.java:71)

      at org.hibernate.impl.SessionFactoryImpl.&lt;init&gt;(SessionFactoryImpl.java:237)
  </code></pre>
  
  <p>(Full stacktrace at the bottom)</p>
  
  <p>I have run <code>mvm dependency:tree -Dincludes=org.apache.commons:commons-collection*</code> but it only shows me classes depending on commons-collections4, I see nothing for that old library.</p>
  
  <p>Is there a way to fix this without adding the old dependency to the pom as well?</p>
  
  <p>I am using hibernate 3.6.0.Final.</p>
