This warning appears on my project when I compile it. I'm using Guice 4.2.1 (maven) and JDK 10
I checked the Travis builds and it seems that the warning appears on travis CI also:
https://travis-ci.org/google/guice/jobs/440573805#L1747
Is there any quickfix?

JDK 10 is still a half baked jvm so I highly recommend moving across, in JDK 10 though with Guice 4.2 i didn't experience any of these. java.lang opening also wasn't required on JDK 10 but is on JDK 11
Very easy to fix...
System.setProperty("com.google.inject.internal.cglib.$experimental_asm7", "true");
Then
--add-opens java.base/java.lang=com.google.guice,javassist

I've released the fully modular guice artifacts based on 4.2.2
All extensions as well
0.70.0.1 is busy going to maven central
guice : https://search.maven.org/artifact/com.guicedee.services/guice/
guice extensions all available -
Current site https://guicedee.com/ - Done the pages up to persistence, should have it all done by the weekend.

Hi All,
Getting this error in maven project with test target. Using
JDK 13 (openJDK 13.0.1)
Surefire plugin 3.0.0-M4
Maven version 3.3.9
WARNING: Illegal reflective access by com.google.inject.internal.cglib.core.$ReflectUtils$1

@alan-hwp are you using Ubuntu's custom distribution of Maven? The official Maven distribution uses the "no-AOP" build of Guice which doesn't contain any CGLIB code. If you download an official distribution from https://maven.apache.org/ then you shouldn't see the warning.

Greetings,
Out team is getting this error when starting our guice-based applications:

So far, this hasn't caused any issues, but we are a bit concerned, given the rate at which OpenJDK updates are becoming more restrictive/secure.
We are running a docker image with the following:
base image: Ubuntu 18.04
java version: OpenJDK_11.0.5.10 (AdoptOpenJDK)
gradle version: 5.4.1
guice version: 4.2.2

Hi @antoinedvd (and anyone else using Ubuntu's build of Maven) this only happens with Ubuntu's build of Maven because they re-bundle it with the AOP enabled Guice jar - the official Apache/Maven distribution ships with the no-AOP Guice jar which does not have this warning.
You can download the official Maven distribution from https://maven.apache.org/download.cgi

Hi @mcculls, you right. Thank you for your advice, it works !
