Description

Simple queries with 2 parameter regex filters fail with NPE. e.g.:

select * where { ?s ?p ?o filter regex(?o, ".*sold.*") }

The error message being printed was the message of the "Cause", but NPEs have neither a cause nor a message. So the name of the exception is being printed. See r1474.



	
The NPE was being caused by the regex class expecting a "flags" parameter, though this is optional. Cleaned up code in several places to handle nulls in this argument. Fixed in r1473.
