Description

It seems that break s are ignored in switch-case statements when @CompileStatic is used.

• Test case 1:
  Test.groovy

  import groovy.transform.CompileStatic
  @CompileStatic
  class Test {
      def test() {
          ['A', 'B', 'C'].each { String val ->
              switch (val) {
                  case 'A' :
                      println("${val} caseA")
                      break
                  case 'B' :
                      println("${val} caseB")
                      break
                  default : 
                      println("${val} default")
              }
          }
      }
  }
  (new Test()).test()
  

Output:

A caseA
A caseB
A default
B caseB
B default
C default

• Test case 2:
  just comment @CompileStatic

And everithing works fine:

A caseA
B caseB
C default
