Good point.  Are you seeing a leak in practice?
The cache is important, especially to inexact MH.invoke.

Well, yes. I am (re)implementing annotations (proxies) using Remi's Proxy2 and made it all the way except for the following failing jtreg test:


...which made me find this issue. What I'm doing is the following:

For implementing some annotation @Ann proxy's hashCode() method for example, I prepare DMHs with the following signature (T)int for Ts being all primitives, primitive arrays, Object[] and Object. I cache them in a system class static field referenced HashMap keyed by Class<T>. These are the functions that take an annotation member value and map it to it's hashCode. When the value is of some Object (or Object[] in case it is an array) subtype - for example when the member value is an annotation of type V, I take the (Object)int DMH and transform it with .asType(methodType(int.class, V.class)) to get (V)int, which is necessary to further wrap it with filterArguments where the filter is a member field getter of type (Ann)V so that I get (Ann)int MHs as a kind of hashCodeExtractors for all annotation members (I'll present the details later)...

I'm curious to see your implementation.
