Description

Unlike Java, Groovy doesn't support multiple labels on the same statement - instead, the AST builder discards all but the first (!) label:

class MultipleLabels {
static void main(args) {
label1:
label2:
while (true)

{ break label1 // OK break label2 // Compile error: "break to missing label" }

}
}
