Extra linefeeds with groovy.xml.XmlUtil.serialize

I get extra line feeds on my mac when running identical code. Does anybody know why this would be?

On Linux… (expected output)

[tauser02@cfmips01ld0s work]$ groovy -v
Groovy Version: 4.0.10 JVM: 1.8.0_362 Vendor: Red Hat, Inc. OS: Linux
[tauser02@cfmips01ld0s work]$ cat test.groovy
String xml = $/<?xml version="1.0" encoding="UTF-8"?><root><elem1 attr1="value1" attr2="value2"/><elem2 attr1="value4" attr2="value4"/></root>/$
def doc = new groovy.xml.XmlParser().parseText(xml)
println groovy.xml.XmlUtil.serialize(doc)
[tauser02@cfmips01ld0s work]$ groovy test.groovy
<?xml version="1.0" encoding="UTF-8"?><root>
<elem1 attr1="value1" attr2="value2"/>
<elem2 attr1="value4" attr2="value4"/>
</root>
