The callback API Callback reports a `JVMBridgeException`, the most useful one is `Throwable` even if the API use the generic `Exception`

[masesdevelopers]

The callback API Callback reports a JVMBridgeException probably the most useful one is Throwable that is a direct extension of JVMBridgeException and it is the most Java aware; the API use the generic Exception:

void onCompletion(RecordMetadata metadata, Exception exception);

Maybe an update can be applied to JNetReflector about this.
