Update JsonJdbcQueryContent.java

[camac]

When returning a jdbc query via json through the Jdbcqueryrest service, there is no check for null when writing the column values.
This means if any column values are null it will throw a null pointer exception and get an Error 500.
This can be handled by checking for null and outputting null , or alternatively you can just ignore it and not output any property ? in any case, it should try to avoid the null pointer exception.

Hi Cameron, we'll review this fix and look to get it included in a post FP8 OpenNTF extlib release.
