--------------------------------------

             Summary: Groovy2 indy not backward compatible missingMethod with Groovy3
                 Key: GROOVY-9681
                 URL: https://issues.apache.org/jira/browse/GROOVY-9681
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
            Reporter: Aleks Tamarkin


I am getting a
{code:java}
Exception in thread "main" java.lang.IllegalArgumentException: array is not of length 1{code}

To reproduce, compile the following in Groovy 2.5 with
{code:java}
groovyOptions.optimizationOptions.indy = true{code}
 
{code:java}
package first

import groovy.transform.CompileDynamic
import groovy.transform.CompileStatic
@CompileStatic class Library {   
    private x 
    Library(x) {
        this.x = x     
    } 
    @CompileDynamic     
    def foo(a, b= '<1>', c= '<2>') {
        "$a" + b + c     
    } 
    @CompileDynamic     
    def methodMissing(String name, args) {        
        foo([(name):x], *args[1..<args.size()])     
    } 
}{code}
Then reference the code in Groovy 3.0.5 to reproduce the error
 
{code:java}
package second 
import first.Library 
class App { 
    static void main(String[] args) { 
        println new Library(2).bar( 'a' )         println new Library(2).bin( 'a', 'b')     
    } 
}{code}
{color:#000000} {color}
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
