---------------------------------------------------------------

The problem is that all Scala objects has a name that ends with '$' character. {{PortableContext.typeName}} returns empty type name and default type mapper resolves {{TypeId}} to {{0}} that is reserved for {{UNREGISTERED_TYPE_ID}} constant. Client Java code also can have classes with similar names.

Another symptom of this bug is {{No class definition for typeId: 0}} message.

Waiting for TC.

> ---------------------------------------------
> DESCRIPTION
> ---------------------------------------------
> When default optimizedMarshaller is changed into portableMarshaller in example-ignite.xml then ScalarPrimeExample doesn't start with exception "Not enough data to read the value"
> ---------------------------------------------
> STEPS FOR REPRODUCE
> ---------------------------------------------
> 1. Build examples project in IDE
> 2.In the example-ignite.xml change property from:
> {noformat}
> <property name="marshaller">
>             <bean class="org.apache.ignite.marshaller.optimized.OptimizedMarshaller"> -->
>                 <!-- Set to false to allow non-serializable objects in examples, default is true. -->
>                 <!-- <property name="requireSerializable" value="false"/>
>             </bean>
>         </property>
> {noformat}
> to
> {noformat}
> <property name="marshaller">
>             <bean class=" org.apache.ignite.internal.portable.api.PortableMarshaller"/>
>         </property>
> {noformat}
> 3. Run ExampleNodeStartup
> 4. Run ScalarPrimeExample
> ---------------------------------------------
> ACTUAL RESULT
> ---------------------------------------------
> Example is failed with exception:
> {noformat}
