Description

@groovy.transform.CompileStatic
class MyClass {
  void method() {
    final cl = { Object[] args -> println "cl: ${args}" }
    cl('c1-1', 'c1-2')
  }
}

class MyClass2 {
  void method() {
    final cl = { Object[] args -> println "cl2: ${args}" }
    cl('c1-1', 'c1-2')
  }
}

new MyClass().method()
new MyClass2().method()

Produces the output:

cl: [[c1-1, c1-2]]
cl2: [c1-1, c1-2]

indicating that the Closure in the statically-compiled MyClass is receiving the arguments wrapped in an additional Object[].
