Tommy Svensson commented on KARAF-5242: --------------------------------------- Strangely, on my MacBookPro: `Darwin Tommys-MBP4 16.6.0 Darwin Kernel Version 16.6.0: Fri Apr 14 16:21:16 PDT 2017; root:xnu-3789.60.24~6/RELEASE_X86_64 x86_64` and jdk: {{java version "1.8.0_131" Java(TM) SE Runtime Environment (build 1.8.0_131-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)}} this does not happen!

I have not read anywhere that java8 is not capable of running > java5 byte code, and when the code is run in unit tests with java8 there is > no problem. So I conclude that this problem resides in Karaf or more probably > Felix which is at the bottom as I understand it. It is with Karaf I have the > problem so it is here I report this. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
