The following JEP with scope "SE" has been moved to the Candidate state:

  482: Flexible Constructor Bodies (Second Preview)
  https://openjdk.org/jeps/482

    Summary: In constructors in the Java programming language, allow
    statements to appear before an explicit constructor invocation, i.e.,
    super(..) or this(..). The statements cannot reference the instance
    under construction, but they can initialize its fields. Initializing
    fields before invoking another constructor makes a class more reliable
    when methods are overridden. This is a preview language feature.

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:
