If the callbacks share a common interface, you could accomplish that
with an interface object.

Thank you TreKing for your advice,
But then in my handleMessage I would have to check with
if (inst instance of Foo)
inst.foocallback();
else if (inst instanceof Bar)
inst.barcallback();
else if (...)
or is there a neater solution, perhaps using polymorphism or a design
pattern of some sort
so that my handleMessage does not quickly turn into a mess?
Thanks,

You don't need separate handlers, you can pass the instance of the
object that is being updated in the handler message, then use one
single handler for the main thread.
