Paul Spencer updated KARAF-7435:
--------------------------------
Description:
Setting a configuration parameter to null throws a NullPointerException. The
specification,
[https://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.configurator.html],
is silent on the use of null as a property value, but includes the following
"If a requested conversion cannot be performed, then the configuration is not
processed and the Configurator implementation should log an error."; in
addition the configuration parameter are stored in a Dictionary structure which
requires a non-null key and non-null value. Although the json format supports
'null' as value and OSGi confutation appears to required non-null values,
should Karaf log something like "Null value for <Property Name> not supported."
instead of throwing a NPE?
