Hasan commented on CLEREZZA-320:
--------------------------------

I also think adding sun.reflect to org.osgi.framework.system.packages.extra is 
the way to go until sun fixes that 5 year bug. But I still don't understand why 
the fix of Karl (https://issues.apache.org/jira/browse/FELIX-2421) cannot help, 
if the FELIX-2421 issue is related to that 5 year bug. Anyway, I wonder how 
much the performance of ssp rendering would improve.

> SSP rendering is slow: 
> scala.tool.nsc.interpreter.AbstractFileClassLoader.findClass needs  a lot of 
> time to be executed
