   I can confirm that you get an error message:
   `--- exec-maven-plugin:3.1.0:exec (default-cli) @ AssertjTest ---
   Exception in thread "main" java.lang.RuntimeException: Uncompilable code`
   
   with Compile on Save on.
   
   Envirnoment:
   Product Version: Apache NetBeans IDE 17
   Java: 17.0.4; Java HotSpot(TM) 64-Bit Server VM 17.0.4+11-LTS-179
   Runtime: Java(TM) SE Runtime Environment 17.0.4+11-LTS-179
   System: Mac OS X version 13.2.1 running on aarch64; UTF-8; de_DE (nb)
   
   Test Code:
   
   ```java
   import java.util.Collection;
   
   public class Main {
   
     static class Foo {
       Integer x;
     }
   
     public static void main(String[] args) {
       Foo x = new Foo();
   
       if (x instanceof Collection<?> col) {
         System.out.println("x is a collection");
       } else {
         System.out.println("not a collection");
       }
     }
   }
   ```
   
   Works without the pattern matching col variable,
   I use CoS in every project and most of them are big, so CoS is an advantage especially when I write test.  It cost me hours to find that, so I would like to see that this get fixed.
