this memory space is shared by all libs in the vm. so maybe your ears are taking up a ton of space and only a small amount is left to the wicket app...its just not the right way to look at the problem. this is not heap space which is allocated for runtime stuff, this is the space used by VM to hold bytecode for classes...it doesnt matter how small the app is or what load it is under...
