From JEP 498:

• JDK 23 deprecated all of the memory-access methods for removal.
• JDK 24 will, by default, issue a warning on the first occasion that any memory-access method is used
• JDK 26 or later will throw an exception whenever a memory-access method is used  
• In releases after JDK 26, we will remove memory-access methods

What do you think of using:

I'm still seeing this in v3.9.11, unfortunately.

I checked the Guice tickets and found google/guice#1909 for Guice 7; linking it here for reference and visibility. Maven is also mentioned in google/guice#1901 for Guice 6. No indication on either of these when this would be fixed in Guice.
