I've done some more profiling. Does anyone know what the "Coldfusion.runtime.NeoPageContext" class does? It seems awefully similar to a "Souped-Up HttpServletRequest" based on methods outlined here: http://www.bennadel.com/blog/758-ColdFusion-GetPageContext-Massive-Exploration.htm
Seems like everything in coldfusion (internal classes, like CustomTag, SettingTag, OutputTag, and CFVariablesScopeFilter, etc have a reference to it). ** What Worries Me** is that in my JRockit Memleak Detector I also found 2 of my CFC's referencing it. Do you think this is the leak, if my CFC's are being cached? To me it looks like a circular reference between the CFC and a NeoPageContext, and if my CFC is cached, I'm in trouble. Can someone verify?
