Anton Vinogradov commented on IGNITE-2947:
------------------------------------------
Found that fix is not full.
Class loaded by external classloader is not stores at appropriate places.
Usage of U.resolveClassLoader(igniteCfg); should solve this.
Fix:

> If to register a specific object with {{BinaryTypeConfiguration}} setting its
> {{typeName}} and load Class of objects of this type using a custom class
> loader passed to {{IgniteConfiguration.classLoader}} then at
> {{BinaryContext}} initialization time the context will not properly register
> this {{BinaryTypeConfiguration}} because it doesn't suppose that the Class of
> the type can be loaded by the custom class loader
> In the code below {{Class.forName}} has to use
> {{IgniteConfiguration.classLoader}} if the latest is set and fall back to
> {{dfltLdr}} otherwise.

> @SuppressWarnings("ErrorNotRethrown")
> public void registerUserType(String clsName,
> BinaryInternalMapper mapper,
> @Nullable BinarySerializer serializer,
> @Nullable String affKeyFieldName,
> boolean isEnum)
> throws BinaryObjectException {
> assert mapper != null;
> Class<?> cls = null;
> try {
> cls = Class.forName(clsName);
> }
> catch (ClassNotFoundException | NoClassDefFoundError ignored) {
> // No-op.

> Also there are several conditions in {{BinaryContext}} that are done for
> {{dfltLdr}}. The same conditions have to be executed for
> {{IgniteConfiguration.classLoader}}.
