Description

Due to JmsMessage specification :
http://docs.oracle.com/javaee/1.4/api/javax/jms/Message.html
There are rules how unknown Values evaluates.

I found 4 violations of specificatoion:
1) Equals expression "=".
"unknownProp = 0" should evaluate to UNKNOWN.
In AMQ it evaluates to FALSE instead.
2) Not equals expression "<>".
"unknownProp <> 0" should evaluate to UNKNOWN, it evaluates to FALSE instead.
3) Or expression "or".
"unknown or false" should evaluate to UNKNOWN. It evaluates to FALSE instead.
4) And expression "and".
"unknown and false" should evaluate to FALSE. It evaluates to UNKNOWN instead.
