Dear Karaf-ers, ASM 5 is released so it may be used in Karaf to get Java 8 support:
"This version is fully backward compatible with ASM 5.0 BETA (itself binary compatible with the 4.x versions) and provides full support for the new Java 8 class format features. However, new dynamic checks have been added in order to make sure that ASM version numbers (e.g. Opcodes.ASM4, Opcodes.ASM5, etc) are correctly used at runtime by subclasses of the ASM classes (as documented in the API). Another major difference is that visitMethodInsn(int,String,String,String) is now deprecated, and replaced with visitMethodInsn(int,String,String,String,boolean) -- in order to support invokespecial and invokestatic on interfaces in Java 8. Visitors declared with the Opcodes.ASM5 version MUST use this new method instead of the deprecated one (old visitors using the Opcodes.ASM4 and using the deprecated method will continue to work). See chapters 5 and 10 of the User Guide (http://download.forge.objectweb.org/asm/asm4-guide.pdf) for more details." I'm not familiar with ASM at all, but I would like to get Java 8 support :) How may I help? Is there already a Karaf 3.1.0 beta version?

You will have a bunch of feature that won't work. I gonna check the version range.
