Description _ rkubacki 2004-07-27 18:43:08 UTC

o.n.mdr.handlers.gen.HandlerGenerator.customImplInfos
is a HashTable<Class,HashSet<String>> object
containing signatures for generated handlers. It
occupies 420kB on heap and it is never GC'ed. 

I do not know why we need this table but if we
really use it should be more memory friendly. At
least there is a lot of repeated method signatures
where we can share strings. Maybe we can
reconsider the whole heavy use of reflection.

Comment 1 Martin Matula 2004-07-28 13:05:41 UTC

Fixed. customImplInfos has been transfored into a LRU cache of a
limited size (5) rather than a static hashmap that is never collected.
