Subject Re: karaf 3.0.1 just prints NullPointerException trying to append a property
Date Thu, 28 Sep 2017 06:42:22 GMT
Karaf 3.x works with Java8. Even Karaf 2.4.x also works with Java8. However, we 
fixed issues with Java8 starting from Karaf 3.0.4.

I just tested 3.0.7 on Java8 without problem.

JB
