Michael Dürig commented on SLING-1895:
--------------------------------------
I'm seeing this right away every time. However whether this results to 'a few
calls' internally or not I cannot say at this stage. Furthermore the issue you
mention should have been fixed with framework-3.0.2 (FELIX-2421).
I'll check whether adding only sun.reflect is sufficient and let you know.
I see 3 ways to handle this:
1. add the required packages to boot delegation
2. close as wont fix and open an issue for the Scala scripting engine adding
the boot delegation solution as a work around instructions
3. further investigate the source of the issue and fix it (probably in Felix)
> sun.reflect.MethodAccessorImpl not correctly boot delegated
