Above code run from Eclipse. Maybe that matters?
XmlSlurper…. No see none of the above issues.

If you add ".normalize()", does that make any difference? I am trying to
determine is there are CR chars in the output. Perhaps piping to od or some
octal/hex dump program.
There are also various parser options/features that might be different on
different platforms.
Does XmlSlurper exhibit the same behavior?
Can you try trimWhitespace and keepIgnorableWhitespace on XmlParser?
There are also setFeature and setProperty methods on XmlParser. I don't think
they will help in your case but they have helped for other tricky XML scenarios.
Cheers, Paul.

This appears to be a Java problem, not a Groovy problem, and possibly an
OpenJDK issue.
I’ve only been able to test this further on my Mac laptop as I cannot install
different versions of Java. Redhat ON LINUX
Java 8 works as expected
I’ve tried Java 10, 11, 17, 18 and 19 and all appear to exhibit this behavior

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