None of our classes has an unexpected high instance count.

Im not sure if youve already done this. So thats why you need to poke around with jmeter, hit the different pages(in different tests) maybe thousands of times(if its a very small leak). Then the difference should be more clear. I once had an error that originated in a hashmap that locked session context, it was very hard to find and was not our error but a 3rd party I used 4 very long days for finding the problem...
It's a little abstract to use a profiler as it will not give you a clear idea as everything originates in class[] int[] etc...

Of course.

Already done, but what we can get? An OOME in our application with the heapdump. Well, we already have one and the most used objects appear to come from Wicket (char[], byte[], String, <class>[], HashMap$Entry, XMLTag, ValueMap, ComponentTag, RawMarkup, HashMap$EntrySet, int[], short[] just to name the largest).
