My two cents: I think it is worth to merge your patches 2/5, 4/5, and
5/5, skipping 1/5 and 3/5. As there is no improvement in current
meta-java, we can explain in the documentation how to add meta-java to
bblayers.conf without adding all stuff. I would also skip 3/5, because
this is a local configuration and everybody can decide if java is needed
or not. If it seems too much, we could add a new sample, for example
local.conf.java.sample, making clear that this is a configuration for java.

Best regards,
Stefano Babic
