Affected tests

• optaplanner

We can fix it at camel-quarkus side by specifying quarkus.native.additional-build-args
-J--add-opens=java.base/java.text=ALL-UNNAMED

Or this can be addressed at quarkus side, there is already a ticket to track it quarkusio/quarkus-quickstarts#993 (not fixed yet)

[zbendhiba]

@ffang Note that we are way behind the Optaplanner version used in Quarkus quickstarts, and Quarkus platform. Check this pending PR #331

[ffang]

Thanks @zbendhiba , and I guess you mean #3311, right?

But no matter what the optaplanner version is used(8.9 or 8.13), they both have this issue with JDK17. The root cause of this issue is from the com.thoughtworks.xstream with jdk17(when option --illegal-access=permit was removed from JDK17)

Out of date. This is now working without any issues.
