> When upgrading from Groovy 4.0.28 to 5.0.0, I notice that compiling the following code started throwing VerifyError:
>  
> {code:java}
> static def test(long x, Long other) {return x ?: other}{code}
>  
> {{Observed exception:}}
>  
> {code:java}
> java.lang.VerifyError: Inconsistent stackmap frames at branch target 23
> Exception Details:
>   Location:
>     Script1.test(JLjava/lang/Long;)Ljava/lang/Object; @18: goto
>   Reason:
>     Current frame's stack size doesn't match stackmap.{code}
>  
>  
> Of course, that code does not make much sense, but a bad refactoring left it like that in my codebase, and after the version upgrade, it broke.
