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

             Summary: each() method does not iterate properly
                 Key: GROOVY-7619
                 URL: https://issues.apache.org/jira/browse/GROOVY-7619
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.3.7
         Environment: OS: Windows 7
Grails: 2.4.4
JDK: 1.8.0_31
            Reporter: Mark Visontai
            Priority: Critical


it seems the each method is erroneous. For the code:
{code}
def xml = new XmlSlurper().parseText('''
<list>
    <item a="1">a</item>
    <item a="2">b</item>
    <item a="1">c</item>
</list>
''')

xml.'**'.findAll { it.@a=='1' }.each {
    println "hi"
}  
{code}

|{code: title=Expected output:}
hi
hi
{code}|{code: title=Actual output:|bgColor=#fcc}hi{code}|

Two result items are only provided if I also print something that is changing between the iterations, eg. a variable with increasing value, like
{code}
def i=0
xml.'**'.findAll { it.@a=='1' }.each {
    println "hi" + i++
}  
{code}

what can be the reason?
Thanks,
Mark
