The annotation module is for bytecode scanning all of your WEB-INF/lib and WEB-INF/classes content. Used to find various bits and bobs related to Servlet 3.x initialization. Used by class annotations (like @Servlet, @Filter, @HandlesType etc), and reference tree construction (eg: types referenced in ServletContainerInitializer's).
If you have 1.5GB of memory used for your annotation scanning you must have a stupendous amount of classes in your webapp. Joakim Erdfelt / [email protected] On Fri, Aug 28, 2015 at 6:33 AM, Ciprian Hacman <[email protected] > wrote: > Unfortunately, the RES Size is not a mistake. > I was hoping to get some feedback from someone with more knowledge about > the annotation module in Jetty, so that I don't have to debug using a > native profiler.
