*===================*
*Steps to Reproduce*
*===================*
*Step-1)* Edit the "etc/org.apache.karaf.management.cfg" file and add the following entry in it. Notice that the "" does not exist as we hav not created any such keystore. And then start the karaf. 

{code}
#####################   ADDING THE FOLLOWING NON_EXISTING SSL KEYSTORE INTENTIONALLY #############
secured = true
secureProtocol = SSL
keyAlias = jbossalias
keyStore = sample_keystore
trustStore = sample_keystore
{code}


*Step-2)* Try stopping the karaf either usign "shutdown" command or using ctrl+d :

*Step-3)* Check the karaf.log to find the "java.lang.NullPointerException"
