BUG Spark 2.5.8/Jingle Plugin: Hardcoded STUN server "stun.xten.net"

Hi,

the JinglePlugin.java contains a hard coded setting of the STUN server to stun.xten.net. This is preventing the complete shut down of external STUN requests by the Spark client. I would consider this a bug as it overrules the STUN configuration in Openfire.

Can this be fixed in 2.6.0 ?

Kind regards,

Walter
