Investigate JEP 361: Switch Expressions

[tgodzik]

JEP 361 introduced switch expressions. Since we are planning to update to a newer JDK at an unspecified future I hope we can figure out if this is in any way useful to use for example for some bytecode optimization.

And if we can actually use them or whether it will be impossible for us.

Introduced in JDK 14

It can't match with null for now, IIRC, there is an new bytecode for type matching, seems slower when the cases are small.
I could like to have scala pattern matching support on Java's record.

I could like to have scala pattern matching support on Java's record.

I wonder if we can get it without updating to the JDK they were introduced at or would this unblock the possibility

With multi release jar？Not sure about that, but if Scala support pattern matching on record and still works on Java 8, that will be very cool.
