IntelliJ IDEA 2020.1 EAP with Records/Patterns support

[Remi Forax]

As a test, i've taken the source of Effective Java (3rd Ed) and change them to use var, switch expression, records and the instanceof with the type test pattern. 
[ https://github.com/forax/effective-java-3e-source-code | https://github.com/forax/effective-java-3e-source-code ] 

IntelliJ works great ! No problem. 

regards, 
Rémi
