Java to Kotlin bug

// The IntelliJ IDEA Kotlin to Java converter generates syntactically invalid
// Kotlin code for the Java code below.
//
// The `break` is not removed, which is invalid in `when`
// expressions. While the code is a bit silly, I faced this problem in the wild
// while converting https://tartarus.org/martin/PorterStemmer/java.txt.
