When will Guice support Java 16?

[danielalmeidagoncalves]

Hi all,

Reading the latest Guice release (5.0.1), now Guice supports java15. What are the plans to support java16? In our project we would like to do the upgrade but we depend on Guice to do the migration.

Thanks in advance!

You can use GuicedEE for JVM modular Guice on all JDK modules,

From my preliminary testing it looks like 5.0.1 may work on java 16 but I'm not sure about your specific use case. I looked at the pom.xml for 5.0.1 and it looks like it is using asm 9.1 which supports up to java 17 https://asm.ow2.io/versions.html.

One notable java 16 feature worth better support is records. For example, the following does not work in Guice right now, though I don't see reasons why it shouldn't:

public record Foo(@Inject Bar bar) {
  ...
}

version 5.1 supports Java 17, so perhaps that's enough? https://github.com/google/guice/wiki/Guice510

In https://github.com/trinodb/trino we are using Guice 5.1.0 since we've switched to JDK 17 in August. Since then, we've released 20+ versions of the software, and we've never encountered any incompatibilities between Guice and JDK17. JDK16 introduced strong module encapsulation by default, so if Guice works in JDK17, I'd expect it to work in 16 as well.
