The following JEP with scope "SE" has been proposed to target JDK 18:

  421: Deprecate Finalization for Removal

  Summary: Deprecate finalization for removal in a future
  release. Finalization remains enabled by default for now, but can
  be disabled to facilitate early testing. In a future release it
  will be disabled by default, and in a later release it will be
  removed. Maintainers of libraries and applications that rely upon
  finalization should consider migrating to other resource management
  techniques such as the try-with-resources statement and cleaners.

The announced deadline for feedback to jdk-dev is Tue 7 Dec 23:59 UTC:


If there are no unresolved objections at that time, then the JEP will be moved
to the Targeted state, indicating that the feature is expected to appear in
the specified release of the JDK Project.  For more information about states,
see the JEP Process document:
