bootstrap method initialization exception raised when lambda parameter type is wrong

    Details

      Description

      The following code will raise BME

      import java.util.stream.*
      
      @groovy.transform.CompileStatic
      def x() {
          IntStream.range(0, 2).forEach((Integer i) -> { assert 0 <= i && i < 2})
          // IntStream.range(0, 2).forEach(i -> { assert 0 <= i && i < 2}) // raise BME too
      }
      
      x()
      

      but the following code works well:

      import java.util.stream.*
      
      @groovy.transform.CompileStatic
      def x() {
          IntStream.range(0, 2).forEach((int i) -> { assert 0 <= i && i < 2})
      }
      
      x()
      

      BME stacktrace:
