[xfire-user] XFire 1.2.6 & JAXB 2.0 version

[Wagle, Shriniwas]

Which specific JAXB 2.0 version is being used with XFire 1.2.6?  E.g.
JAXB 2.0.1 or 2.0.2 or 2.0.3?
 
Is there some easy way for me to determine that?
 
Can I upgrade the JAXB version to 2.1.4 by getting the reference
implementation from https://jaxb.dev.java.net/?  If yes, how can I do
that and then is there a way to validate that the upgrade has been
successful?
 
Thank you.
