Description

The method pointer operator suppresses checked exceptions and results in a MethodMissingException instead in groovy 4.0.12. This issue seems to first appear in groovy 3.0.16, which is the earliest version I am able to reproduce. Example code

class Foo {
    static void bar(String str) {
        throw new IOException()
        println str
    }
}
def baz = Foo.&bar

baz('hi') 

This results in a MethodMissingException despite the IO Exception being thrown. This seems to be the case for any checked exception.

 

class Foo {
    static void bar(String str) {
        throw new IOException()
        println str
    }
}

Foo.bar("hi") 

When calling the method directly I get an IO Exception as expected
