> Key: GROOVY-11858

> Project: Groovy
> Issue Type: Bug
> Affects Versions: 5.0.4
> Reporter: Evan Shaw
> Assignee: Eric Milles
> Priority: Major
>
> This code throws an exception:
> {code:groovy}
> 'a b c'.tap { println(split()) }
> {code}
> The exception message:
> {code}
> NullPointerException: Cannot invoke
> "groovy.lang.Closure.getMaximumNumberOfParameters()" because "wrapped" is null
> {code}
> If I pass an argument to split, it works as expected:
> {code:groovy}
> 'a b c'.tap { println(split(' ')) }
> {code}
