Dan Haywood reassigned ISIS-2054:
---------------------------------

         Assignee: Andi Huber
    Fix Version/s:     (was: 1.18.0)
                   2.0.0-M2

This ticket has had commits on it for v2 (M2).  The idea was to backport to 1.x codebase, but I don't think there's any point in doing so.

> Comment by Andi ...
> think this relates to just noticed we can improve performance of specloader initialization by tweaking ... org.apache.isis.core.metamodel.facets.Annotations such that annotation lookup does no longer call getMethod(byName, ...) 
> this produces a huge amount of stack-trace objects that pollute the heap
> This has already been parallelized, but I think the bottleneck could be memory related :)
