It's also now available on the SRX as of 12.1X44D10.  

One to watch though - Mac OSX and most other non-windows clients will fail to get an address from the JDHCP daemon because they set the BOOTP Unicast flag on all requests, whereas Windows will fall-back to broadcast after 30 seconds.  The following command will fix it even though the text of the knob says the complete opposite of what it seems to do:

set system services dhcp-local-server group BLAH interface BLAH overrides no-unicast-replies
(or under your routing-instance)
