Alexander Paschenko commented on IGNITE-6314:
---------------------------------------------
[~vozerov]
Mapper affects {{IgniteCache.get}} behavior by design: when we change mapper,
we change class name in {{BinaryClassDescriptor}} (it ends up lacking package
part) and thus {{IgniteCache.get}} without {{withKeepBinary}} justly fails
(Ignite tries to deserialize object with non-existent class {{City}}).
What can be done: I suggest that upon starting a cache we proactively register
real value type with {{BinaryContext#registerUserClassName}} - if we do so,
then by the time first user operation occurs, cluster will already have class
descriptor with correct (non-trimmed) type name, and id of that descriptor will
match that of descriptor for trimmed type.
