Hello We are interested in backporting RESTEASY-2648 to 3.15.x. In the JIRA [1] there was a discussion about backporting to 3.13.x but it looks like this never happened. We are interested in RESTEASY-2648 because we would like to get rid of the Guava dependency when using the Jackson 2 provider in a Java SE environment. We are still on 3.15.x because we are using RESTEasy both in WildFly and in Java SE and we would like to keep the versions in sync, and WildFly is still on 3.15.x. Is this something you would be acceptable? If so we would be willing to work on a PR. What would be involved other than cherry picking the commit [2], cloning the JIRA and opening a PR?
