Description

class Example {
    static byte[] hash(byte[] bytes) {
        bytes
    }
    static class Nested {        
        def getCacheKey(byte[] payload) {
            hash(payload)
            // hash(payload as byte[]) fails as well 
            // Example.hash(payload) works
        }
    }
}

new Example.Nested().getCacheKey("bar".bytes)

fails with

groovy.lang.MissingMethodException: No signature of method: static Example.hash() is applicable for argument types: (ArrayList) values: [[98, 97, 114]]
Possible solutions: hash([B), each(groovy.lang.Closure), wait(), any(), wait(long), is(java.lang.Object)
