### Affected version

### Bug description

```
mvn help:evaluate -q -Dexpression=project.properties -DforceStdout
```
on jdk 25 return warnings on top before print properties
```
WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
WARNING: sun.misc.Unsafe::objectFieldOffset has been called by com.thoughtworks.xstream.converters.reflection.SunUnsafeReflectionProvider (file:/home/user/.m2/repository/com/thoughtworks/xstream/xstream/1.4.20/xstream-1.4.20.jar)
WARNING: Please consider reporting this to the maintainers of class com.thoughtworks.xstream.converters.reflection.SunUnsafeReflectionProvider
WARNING: sun.misc.Unsafe::objectFieldOffset will be removed in a future release
```

Reproduce the `mvn help:evaluate -q -Dexpression=project.properties -DforceStdout` command with JDK 25 and inspect the warning source, especially XStream 1.4.20 and `SunUnsafeReflectionProvider`. Confirm the fix by ensuring the command outputs the properties without the `sun.misc.Unsafe` warnings.
