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

  420: Pattern Matching for switch (Second Preview)

  Summary: Enhance the Java programming language with pattern matching
  for switch expressions and statements, along with extensions to the
  language of patterns.  Extending pattern matching to switch allows
  an expression to be tested against a number of patterns, each with a
  specific action, so that complex data-oriented queries can be expressed
  concisely and safely.

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:

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
