The following JEP with scope "SE" has been moved to the Candidate state:
500: Prepare to Make Final Mean Final
https://openjdk.org/jeps/500
Summary: Issue warnings about uses of deep reflection to mutate
final fields. These warnings aim to prepare developers for a future
release that ensures integrity by default by restricting final field
mutation, which will make Java programs safer and potentially faster.
Application developers can avoid both current warnings and future
restrictions by selectively enabling the ability to mutate final fields
where essential.
A JEP in the Candidate state is a feature deemed worthy of consideration by
the JDK Project, but with no commitment to deliver the feature in any
particular release of the JDK Project. Later, the JEP may be moved to the
Targeted state, which indicates that the feature is expected to appear in a
specific release of the JDK Project. For more information about states, see
the JEP Process document:
https://openjdk.org/jeps/1
A JEP with "SE" scope that reaches the Targeted state will be listed in the
Specification of the Java SE Platform JSR which corresponds to the targeted
JDK Project release.
A dashboard that lists JEPs with "SE" scope may be found via a link on this
page:
