> Hello,
> We are working on performance improvements while load testing the application, and I noticed that ResourceBundleMapWrapper uses arounbd 140 Ko per Serving thread, in our configuration with around 1000 thread, this is a big memory impact.
> I started investigating the class and code seems strange to me, in fact I don't understand why InternalRbmWrapper constructor copies creates a Map by copying content of ResourceBundle.
> Why not only have a reference and delegate calls to the ResourceBundle ?
> Furthermore since put methods throw RuntimeException, I really don't see any case where the Map will change.
> I made a test removing this code and delegating to resourceBundle and it seems OK.
> If someone knows why it was made like that I would really be interested, if there is no reason I will submit a patch
> Thank you
> Regards
> Philippe
