Garret Wilson commented on MNG-8399:
------------------------------------
I'm actually getting two warnings with Maven 3.9.9 using the released Java
24+36 on Windows:
{code}
WARNING: A restricted method in java.lang.System has been called
WARNING: java.lang.System::load has been called by
org.fusesource.jansi.internal.JansiLoader in an unnamed module
(…/maven/lib/jansi-2.4.1.jar)
WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for callers
in this module
WARNING: Restricted methods will be blocked in a future release unless native
access is enabled
WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
WARNING: sun.misc.Unsafe::objectFieldOffset has been called by
com.google.common.util.concurrent.AbstractFuture$UnsafeAtomicHelper
(…/maven/lib/guava-33.2.1-jre.jar)
WARNING: Please consider reporting this to the maintainers of class
com.google.common.util.concurrent.AbstractFuture$UnsafeAtomicHelper
WARNING: sun.misc.Unsafe::objectFieldOffset will be removed in a future release
{code}
It looks like this has already been fixed in Guava
([issues/7565|https://github.com/google/guava/issues/7565]). It has been noted
in Jansi ([issues/301|https://github.com/fusesource/jansi/issues/301]).
