Guillaume Nodet commented on KARAF-2562:
----------------------------------------
Just fwiw, I see 3 main uses of ASM: aries-proxy, jetty and pax-web (through
xbean).
The first 2 ones are optional requirements and karaf should be able to work
without ASM.
For pax-web/xbean, this dependency is not flagged as optional in the OSGi
metadata, not sure if it could be made optional.
Anyway, i've uninstalled asm and refreshed, and karaf seems to be working
sanely (tested on 2.x though).
