Jenkins artifactory plugin 2.15.0 with exception related to this module

[Pistahh]

Our Jenkins pipeline worked fine on Jenkins 2.60 + Artifactory plugin belonging to that version; after upgrading Jenkins to 2.113 and Artifactory plugin to 2.15.0 we see exceptions related to this module.

With Jenkinsfile:

node('ubuntu') {
    stage('Test') {
        def artifactoryServer = Artifactory.server('repo')
        def buildInfo = Artifactory.newBuildInfo()
        def spec = '{"files": [{"regexp": "false","flat": "true","pattern": "xy-local-test/current/*","target": "out/"}]}'
        sh 'mkdir -p out'
        artifactoryServer.download(spec, buildInfo)
        echo "downloaded"
    }
}

we get the following exception:

java.lang.NumberFormatException: null
	at java.lang.Long.parseLong(Long.java:552)
	at java.lang.Long.valueOf(Long.java:803)
