Description

I am getting a

Exception in thread "main" java.lang.IllegalArgumentException: array is not of length 1

To reproduce, compile the following in Groovy 2.5 with

groovyOptions.optimizationOptions.indy = true

 

package first

class Library {   
    def foo(a, b= '<1>', c= '<2>') {
        "$a" + b + c     
    }      
    def methodMissing(String name, args) {        
        foo(name, *args[1..<args.size()])     
    } 
}

Then reference the code in Groovy 3.0.5 to reproduce the error

package second 
import first.Library 
class App { 
    static void main(String[] args) { 
        println new Library().bar( 'a' )        
        println new Library().bin( 'a', 'b')     
    } 
}

 
Note that if both are compiled with Groovy2 or Groovy3 the error does not occur.

This is probably similar to https://issues.apache.org/jira/browse/GROOVY-9515?jql=text%20~%20%22%5C%22array%20is%20not%20of%20length%201%5C%22%22
