Salut Yoann,
Thanks for logging this, we'll have a look at it.
Also very happy that the other projects pass on JDK 18 EA23! ;-)

Hello David,
I'm glad to see that the Outreach program continues and seems in
good hands.
We actually have a bug to report this time, most likely related to
JEP 416: https://bugs.openjdk.java.net/browse/JDK-8277451
Here is the detail per project:

JDK-8277451.

Sanne & Yoann,
I’m happy to announce that moving forward Oracle’s Java DevRel
Team will manage the Quality Outreach Program. I would like to
thank Rory for all the efforts he's put into this program and
wish him all the joy and happiness that retirement can bring!
We have big shoes to fill but we’re excited to continue
building off the amazing structure Rory has put in place.
The JDK 18 schedule is now known [1] with a feature freeze
date (Rampdown Phase One) less than 4 weeks away! This time,
we have 2 important heads-ups, one related to JEP 411
(Deprecate the Security Manager for Removal), and one related
to JEP 416 (Reimplement Core Reflection with Method Handles).
We're asking your help to test and confirm that your project
works seamlessly now that those 2 JEPs are integrated in the
JDK 18 Early-Access builds.
[1] https://openjdk.java.net/projects/jdk/18/
# JEP 411 - Deprecate the Security Manager for Removal
Starting JDK 18 b21 [2], the default value of the
'java.security.manager' system property is set to "disallow".
This means that any application or library that enables the
Security Manager by calling `System.setSecurityManager` will
now have to specify `-Djava.security.manager=allow` on the
command-line in order for that code to continue working as
expected. This change was originally targeted for JDK 17, but
after some discussion/feedback from the community, the change
was delayed until JDK 18 [3].
[2] https://bugs.openjdk.java.net/browse/JDK-8270380
[3] https://openjdk.java.net/jeps/411#Description
# JEP 416 - Reimplement Core Reflection with Method Handles
JEP 416 [4] reimplements `java.lang.reflect.Method`,
`java.lang.reflect.Constructor`, and `java.lang.reflect.Field`
on top of `java.lang.invoke` method handles. Making method
handles the underlying mechanism for reflection will reduce
the maintenance and development cost of both the
`java.lang.reflect` and `java.lang.invoke` APIs. This is
solely an implementation change but we encourage you to test
your project to identify any behavior or performance regressions.
