Bram de Kruijff commented on AMDATU-552:
----------------------------------------

Yes, but they are resources from a bundle (and the classloader is tied to the 
service lifecycle) I see no problem with using that. Tricky part is loading 
custom libraries into a centralized classloader and, thinking about it, that 
would break some modularization as jsp1 can't use taglib (v1) at the same time 
that jsp2 uses taglib (v2).

> Currently the JSP support component creates a new instance of 
> ResourceProviderJspServlet each containing their private JasperClassLoader. 
> Although I have not profiled this yet I have a feeling that this will quickly 
> become a (permgen) bottleneck when a significant amount of (multi-tenant) JSP 
> servlets gets registered. Can we share (part of) the classlaoders?
