NPE when invoking "scr list" with no components registered
----------------------------------------------------------
Key: FELIX-1238
URL: https://issues.apache.org/jira/browse/FELIX-1238
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-1.0.8
Reporter: Filippo Diotalevi
Priority: Minor
Fix For: scr-1.0.10
The bug can be reproduced with a minimal Felix+SCR container like:
[ 0] [Active ] [ 0] System Bundle (1.8.0)
[ 1] [Active ] [ 1] Apache Felix Shell Service (1.2.0)
[ 2] [Active ] [ 1] Apache Felix Shell TUI (1.2.0)
[ 3] [Active ] [ 1] Apache Felix Bundle Repository (1.4.0)
[ 7] [Active ] [ 1] Apache Felix Declarative Services (1.0.9.SNAPSHOT)
In these condition, typing "scr list" in the shell causes a NPE:
-> scr list
No components registered
Id State Name
Unable to execute command: java.lang.NullPointerException
java.lang.NullPointerException
at org.apache.felix.scr.impl.ScrCommand.list(ScrCommand.java:161)

The same happens trying to list components of a non-DS bundle
-> svn list 3
Bundle 3 declares no components
