Description

App Engine Standard for Java 8 (currently in Alpha) lifted the old sandbox/API restrictions. We can now use Objenesis as-is. A recent patch was merged into Objensis to take this new environment into account.

See https://github.com/easymock/objenesis/issues/51

This is tracking issue to ensure that Spring core will use the new version when it becomes available on Maven.

Just wanted to add a precision:

Objenesis 2.6 works perfectly on GAE on Java 8
Objenesis 2.6 will behave as it used to on GAE on Java 7 which is
Call no constructor if the class is serializable
Call the no-arg constructor otherwise

And then, there is 3 things I should have mention a long time ago:

Maybe shading Objenesis isn't a good idea. Objenesis has a stable API. It hasn't changed for years. Only the code under the hood is changing. So not shading would allow users to update easily.
Right now, Objenesis is static in ConfigurationClassEnhancer. So there is no way to easily specify a custom strategy even though SpringObjenesis allows it. It would be useful to change that to get flexibility
SpringObjenesis seems to contain some (not all) stuff that could go down in Objenesis directly. I will have a better look but you can file an issue (or PR) about it

Objenesis 2.6 is in Spring Framework master and therefore 5.0.0.BUILD-SNAPSHOT now. I'll keep this ticket open until it's upgraded in the 4.3.x branch as well.

Juergen Hoeller I've moved the 1.5.5 release date to July 20. It might be a bit of a light release, but I think the dependency upgrade alone makes it worthwhile.

While waiting, here is a cute hack to make it work right now. If it can be of any help. It could even go in the real SpringObjenesis.java version. But I'm not sure the shading plugin will like that.
