This backdoor of ECACEH must be closed

I just found out today that ECACHE has an error in the log:
{INFO } [2014-06-30 07:42:10,625] <net.sf.ehcache.util.UpdateChecker> : New update(s) found: 2.6.5 [http ://www.terracotta.org/confluence/display/release/Release+Notes+Ehcache+Core+2.6]. Please check http://ehcache.org for
the latest version.
After checking the information, I found that ECACHE By default, it will link to the website to see who is using it. This is unsafe behavior and must be closed, even if it is on the intranet. Method:

Open ehcache.xml and change the attribute updateCheck of the first line of <ehcache> to false. For example the following:
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false">
