MapMessage conversion layout %K not working

Hi log4j2 users,

I have created a MapMessage with a key-value pair

e.g. userName="log4j"

I have configured JDBCAppender with 

<Column name="userName" pattern="%K{userName}"/>

But, it gives null pointer error when tried to insert into database table using %K/%map/%MAP
and works when you put normal message/literal string.

Note: 
'userName' is same for Column-name, pattern and MapMessage-key as well.
Using log4j version 2.9.0

Please help,

Thanks,
Gaurav
