Description

• Clone the repository https://github.com/huxi/bugs
• cd bugs/groovy/calls-with-null
• ./gradlew

The example class has three public static 'toStringSpecial' methods. It's impossible to call toStringSpecial(Set) or toStringSpecial(String) with a null argument.

This is possible in Java by casting null to the desired type.

It's currently impossible (AFAIK) to use Spock for testing such Java methods.
