[Cellar] register a custom serializer

[Cristiano Costantini <cr...@gmail.com>]

Hi all,

does anyone has ever successfully registered a custom serializer in the
Cellar's Hazelcast instance?

I'm having problems... if I configure a serializer like this:
<serializer type-class="net.cristcost.data.MyUnserializableData"
class-name="net.cristcost.serializer.OsgiSerializer" />

and even if I've fragmented the Hazelcast bundle with a bundle that
contains the two above classes, I get a class not found exception on the
type class of the serializer:
