Please push the latest code to maven

[Damon Snyder]

Hi Mark, do you mind pushing the latest code to maven? I'm having an issue with NPEs deserializing maps that have null values. I think this commit will probably resolve the issue since the root of the problem is in ImmutableMap.

Thanks!
Damon

Unfortunately that commit won't help as that's after I started switching to using Javaslang in core, which has now moved to being a backwards incompatible API ( of which a newer implementation of JsonRepresentationReader/Writer exist). I do need to make a support release soon that I've been to do to resolve an issue for Android usage.

Do you have an example hal+json document I can use to add a test-case?

Can you post the NPE stacktrace?

Here is the HAL document that is causing the issue. It came from this API.

Here is the NPE stacktrace:
