JON remote API getBundleFiles() returns null when criteria fetchBundleFiles is not explicitly set to true

Issue

• When invoking bundle.getBundleVersions().get(0).getBundleFiles().size() the following exception is thrown:

  Exception in thread "main" org.rhq.enterprise.client.script.CLIScriptException: javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: TypeError: Cannot call method "size" of null (<Unknown source>#53) in <Unknown source> at line number 53

• getBundleFiles() returns null

• Why do I not get a list of bundle files associated with a bundle version?
