Description of problem:
When trying to create new JMS Queue, "Redistribution Delay" default value
should be "-1" but in UI it's just "-" so the user has to change it. Also,
it's not possible to set it to "-1".

Version-Release number of selected component (if applicable):
JON 3.0.1

How reproducible:
Always

Steps to Reproduce:

1. In JON UI, select JBoss instance with HornetQ and navigate to JMS Manager;
2. Right click on JMS Manager and from the drop down menu choose "Create Child"
and JMS Queue;
3. Follow the screens in the "Resource Create Wizard" and define values for:
New Resource Name, Name and JNDI Name;
4. Scroll down to check the default value for "Redistribution Delay". This is
set to "-" although the description next to this field says that "-1" is the
default value which means "do not re distribute".
5. Press "Finish" button without changing "Redistribution Delay" value;  

Actual results:
The Wizard screen will not close and exclamation sign will be shown next to the
"Redistribution Delay" field. 

Expected results:
The "Redistribution Delay" default value is properly set to "-1" and the queue
can be created without changing this field.

Additional info:
Please note that attempt to set this field to "-1" will not work as well.
