Ok, well, I just tried making karaf use 1.7.0_131, and the problem no longer 
occurs.  I guess I'm going to move forward with that.

I realized that although the console doesn't tell me much, the log file would 
tell me more.

I found the NPE in the log, and there was also another exception before it.  
Here's an excerpt that includes both:

Re: karaf 3.0.1 just prints NullPointerException trying to append a property

2017-09-27 Thread Jean-Baptiste Onofré 
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

The reason might have been the ASM stuff, so I wouldn't rely on that.

If you want to use Karaf 3.0.x you'll need to stick to Java 7 I fear.

Hi David,

Something is wrong on 3.0.1 (at least with Java 8): all commands throw a
NullPointerException (even a simple bundle:list).

After a quick look, it seems to be related to blueprint and aries proxy (and
asm).

I'm checking and I will fix that.

JB

I need to make, and I don't even regularly use karaf.

The setup process requires entering some commands into karaf after it
starts up.  First there's a call to "config:property-append" with
certain parameters.  When I do this, or even just
"config:property-append --help", it just says "Error executing command:
java.lang.NullPointerException", with no other information.

What might be wrong here, and what can I do to get more information?

Assuming I get this working, is it practical to pipe a set of commands
into karaf, so it will enter them after it presents the command prompt?
