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?

Regards,
JP

It's exactly what I suspect about Aries Proxy and ASM.

You will have a bunch of feature that won't work.

I gonna check the version range.
