Summary

JEP 409 proposes that the Sealed Classes feature is ready to be made final and permanent. Currently the javax.lang.model APIs only support Sealed Classes as a preview feature. Making the feature standard in Java will affect these APIs.

Problem

The preview status of javax.lang.model APIs that support the Sealed Classes feature should be updated so that they can be used in standard Java.

Solution

Update javax.lang.model APIs that support the Sealed Classes feature so that they can be used in standard Java
