Why activemq 4.1.1 instead of 4.1.2?

[David Jencks]

Why does the activemq 4 module use 4.1.1 rather than 4.1.2?  From svn  
log it looks like the activemq4 support is brand new but the one log  
comment makes it look like maybe it isn't and this is really old code  
that never got updated?

thanks
