Description
If default comes before a case and simply continues into that case
default:
case DERIVATION_MODE:
System.out.println("default");
break;
refactoring with org.openrewrite.staticanalysis.DefaultComesLast from org.openrewrite.recipe:rewrite-static-analysis:1.6.0 results in a duplicate case and code duplication
case DERIVATION_MODE:
System.out.println("default");
break;
case DERIVATION_MODE:
default:
System.out.println("default");

Research direction
Start by reproducing the Java switch example with org.openrewrite.staticanalysis.DefaultComesLast from rewrite-static-analysis:1.6.0, then inspect the recipe implementation and its existing tests. Done means the transformation no longer creates a duplicate case or duplicates the default branch, with a regression test covering this input.
