             Summary: CPP: Incorrect Compute task failure handling
                 Key: IGNITE-19055
                 URL: https://issues.apache.org/jira/browse/IGNITE-19055
             Project: Ignite
          Issue Type: Bug
            Reporter: Mikhail Petrov


All calculation methods, except for those whose names contain the word "affinity", fail to  handle errors that occure during task execution.

They just fail with the following message:

{code:java}
Broken promise. Value will never be set due to internal error.
{code}

It appears that the CPP  IgniteEnvironment::ComputeTaskComplete method does not deserialize the exception information at all, which is generated by the Java side (see PlatformAbstractTask#onDone).

DotNet does not have such problems due to the correct implementation of exception info deserialization (see Apache.Ignite.Core.Impl.Unmanaged.UnmanagedCallbacks.ComputeTaskComplete).
