Hi,
thank you for you patch!

Why should one recipe, altough it conains multiple packages have only
one dbg package? Shouldn't the openjdk-8-demo-dbg package contain the
debug information for the openjdk-8-demo package?

This may be OE's policy, if one recipe contain multiple -dbg package , other 
-dbg packages all will be
a empty pacakge, only have one will contain all .debug file,  you can see the source 
"meta/classes/package.bbclass"

But obviously the demo-dbg package isn't empty because it has its "FILES" 
defined ;-)

Nonehteless according to my first quick test the demo-dbg package
contains lots of other debug information too...
So maybe it would be the better way to fix the content of the different
dbg packages rather than removing one?

I also thought this, but  after discussing with the other guys,  the result is 
a recipe can only have
a -dbg package, and this is OE's policy.

Do you have a pointer to this discussion (or if it exists to the according 
documentation) for us?

For oe-core's recipes, each recipe only has one dbg package, split dbg packages
doesn't make any sense since they usually can't be run independently. Please
see oe-core's commit:

commit a3b000643898d7402b9e57c02e8d10e677cc9722

    meta: more removals of redunant FILES_${PN}-dbg

    In some recipes overly-split -dbg packages were merged into PN-dbg.  Unless
    there's a very good reason, recipes should have a single -dev and -dbg 
package.
