Description

Here is my code

def cityList = '''\
1 San Francisco
2 Cupertino
'''
def cityMap = cityList.split('\n').
    collectEntries{ it.split(' ', 2).toList() }
    
def cityMap2 = cityList.split('\n').
    collectEntries{ it.split(' ', 2) }

I initially only tried the second approach, and got an exception that was rather hard to debug:

Exception thrown

java.lang.ClassFormatError: Illegal class name "String;4_groovyProxy" in class file String;4_groovyProxy
	at ConsoleScript6.run(ConsoleScript6:8)

Gold would be if Groovy deals with this out of the box.
Silver would be if the error message told me what was wrong.

Note

Issue split - this part is to handle the incorrect naming for arrays with ProxyGeneratorAdapter
