Error when testing CentraSite connection in IS Admin Page->Metadata


I have installed latest trial version of webMethods ( 9.8 ) and latest CentraSite trial version (9.5) with default values/ports.I’m trying to set up the connection of Centrasite by accesing IS Admin Page->Metadata .The CentraSite URL is http://localhost:53305/CentraSite/CentraSite .When testing the connection I get below error :
error: net.sf.ehcache.Cache.setStatisticsEnabled(Z)V
I would really appreciate your help in getting this issue fixed.Thank you.
