Issue Type: Bug Bug

Description:

I have been trying to use Workflow to check out a secured Subversion repository.

My script is this:
def creds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(
com.cloudbees.plugins.credentials.common.StandardUsernameCredentials.class,
Jenkins.instance,
null,
null
);
def cid = creds[0].id
node { checkout scm: [ $class: "SubversionSCM", locations: [ remote:'https://secure3.svnrepository.com/myrepo/trunk', credentialsId: cid] ] }

I have only one credential stored in Jenkins, the one for the svn repo, so that's why I am grabbing it programatically.

The output is:
Running: Allocate node : Start
Running on master in /var/jenkins_home/workspace/WorkflowTest
Running: Allocate node : Body : Start
Running: General SCM
Running: Allocate node : Body : End
Running: Allocate node : End
Running: End of Workflow
