Description

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)
at org.apache.felix.scr.impl.ScrCommand.execute(ScrCommand.java:102)
at org.apache.felix.shell.impl.Activator$ShellServiceImpl.executeCommand(Activator.java:291)
at org.apache.felix.shell.tui.Activator$ShellTuiRunnable.run(Activator.java:177)
at java.lang.Thread.run(Thread.java:637)

The same happens trying to list components of a non-DS bundle
-> svn list 3
Bundle 3 declares no components
Id State Name
Unable to execute command: java.lang.NullPointerException
java.lang.NullPointerException
