> Upon {{GridClientCompute.execute()}} I get non-informative error if a task class is not
present in {{classnames.properties}}. It occurs when {{GridClient}} was configured to use
{{GridClientOptimizedMarshaller}}.
> {noformat}
> Closing NIO session because of unhandled exception [cls=class o.a.i.i.util.nio.GridNioException,
msg=class o.a.i.IgniteCheckedException: Failed to deserialize object with given class loader:
null]
> {noformat}
> There is two problems:
> * Actual problem was hidden
> {noformat}
> Caused by: java.lang.UnsupportedOperationException
>     at org.apache.ignite.internal.client.marshaller.optimized.GridClientOptimizedMarshaller$ClientMarshallerContext.className(GridClientOptimizedMarshaller.java:137)
>     at org.apache.ignite.internal.MarshallerContextAdapter.getClass(MarshallerContextAdapter.java:174)

> {noformat}
> * Even reading the cause we don't understand what is wrong
> What to do:
> * Log stacktrace every time
> * Throw UnsupportedOperationException with informative message.
