That's one way of solving it.
But AdvancedCache::with(CL) already solves this problem - that's why I used it (I
remembered later :-)).
But that only helps during serialization - not deserialization where
this classloader is no longer available, thus class resolution will
fail.
Where I think the two: AC::with(CL) and ServiceModuleLoader impl of
ClassResolver, should no be connected.
Since they solve diff problems, imo.
True, but with(CL) can really only be used (e.g. in a cluster, with a
cache store, etc.) if storeAsBinary is enabled - for the reason
mentioned above.
Anyway, I'm now gonna try and hunt down where plain ML impl of CR
somes in ...
