I've never tried using gst1-java-core with the package from brew.

Try running in a terminal (checking the command name is correct) -

gst-inspect-1.0 webrtcbin

Does that show help or a missing plugin?

If missing, then it's possible that brew doesn't included that element. If that works, then I would guess paths are not configured correctly in your code.

Yes it seems gstreamer does not include it:

No such element or plugin 'webrtcbin'

Is there away to include it ?

Ask brew upstream, or check out the GStreamer project's own packages.
