I have few ideas why it might happen, but in order to fix this faster - can you please write a unit test that reproduces the problem?

It seems that `io.protostuff.MapSchema.MessageFactories` should contain an entry for `java.util.Properties`.

Fixed in version `1.5.5`

@gaigeshen please check if problem is resolved.

It's quite tricky problem. There is no deterministic way to convert java code to protobuf descriptors. For instance, there are many things that are available for java serialization but are...

AFAIK there are no alternatives.

I started work on gradle plugin in my repository: https://github.com/kshchepanovskyi/protostuff-gradle-plugin Comments/suggestions are welcome.

@dyu do you plan to support Java 9/10 for protostuff-runtime?

Unlikely, no time / need for me. I do not have any projects using protostuff-runtime.

Can you please write some unit test that will show a problem?
