Configuring the Update Checker
The update checker is used to see whether you have the latest version of Ehcache. It is also used to get non-identifying feedback on the operating system architectures using Ehcache. To disable the check, do one of the following.
Set the following system property:
     -Dnet.sf.ehcache.skipUpdateCheck=true
Set the updateCheck attribute in the outer echace> element in the ehcache configuration file. This attribute is false, by default.
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
  xsi:noNamespaceSchemaLocation="ehcache.xsd"    
  updateCheck="false" 
  monitoring="autodetect" 
  dynamicConfig="true">
