title: MetadataCacheAttributeSource class
body: <p>My application hosted on weblogic 12c server shows a stuck thread that is caused by attribute method of MetadataCacheAttributeSource class: 
  at org.springmodules.cache.interceptor.MetadataCacheAttributeSource.attribute(MetadataCacheAttributeSource.java:53) 
  The attribute method calls the get method of HashMap class: 
  at java.util.HashMap.get(HashMap.java:303) </p>
  
  <p>I believe this class is bundled with spring-modules-cache.jar.
  Is a new version of this jar available with synchronized implementation of the HashMap ?</p>
