Groovy - Jenkins Pipeline - Groovy CPS doesn't go trough .eachLine method

I am trying to run this code inside Jenkins Pipeline script:

def getTags = { svnurl ->
    def command = ["svn","ls","${svnurl}"];
    def proc = command.execute()
    proc.waitFor()

    proc.in.eachLine {
        println(it)
    }    
}

getTags('http://svnurlexample.net/');

The result should be a list of folders at the svn location but what I am getting is an error:

[Pipeline] echo:

1.0.0/

expected to call java.lang.ProcessImpl$ProcessPipeInputStream.eachLine but wound up catching org.jenkinsci.plugins.workflow.cps.CpsClosure2.call

The proc.in.eachLine is causing the issue, as if Groovy finds the first folder on the location but can not handle the rest and reports an error.

This is what worked for me:

@NonCPS
def getTags (svnurl) {
    def command = ["svn","ls","${svnurl}"];
    def proc = command.execute()
    proc.waitFor()

    proc.in.eachLine {
        println(it)
    }    
}

getTags('http://svnurlexample.net/');
