Because that could be quite logical, maybe tomcat 7 needs a lot more data because of that annotation scanning Doesn't it load in way more classes? All that processing and then also maybe loading in up front way more classes then before will mean that the heap (and none heap in this scenario) is already way more loaded. johan
