Description of problem:
Creating channel with GPG key specified fails with "Invalid GPG Url".


Version-Release number of selected component (if applicable):
Satellite-5.7.0-RHEL6-re20141024.0
spacewalk-java-2.3.8-50.el6sat.noarch


How reproducible:
always


Steps to Reproduce:
1. Via API:
   mystruct = {
     "url" : 'file:///etc/pki/rpm-gpg/SOMEKEY',
     "id" : '2CF02A42',
     "fingerprint" : 'A73B 0A91 6F6C 660C D371  881A F2BC 50DC 2CF0 2A42'
    }
    ret = client.channel.software.create(key, CHANNEL, \
        	                         'Name %s' % CHANNEL, \
                	                 'Summary %s' % CHANNEL, \
                        	         ARCH, PARENT_CHANNEL, CHECKSUM, \
                                         mystruct)
2. Also reproducible via API with same values


Actual results:
xmlrpclib.Fault: <Fault 1207: 'redstone.xmlrpc.XmlRpcFault: Invalid GPG Url'>


Expected results:
Should work.


Additional info:
Maybe this is caused by spacewalk.git commit 52823167b0b7b0c9377b0b316c60c2fc1db22c59 because is makes the URL uppercase and then tries to match GPG_URL_REGEX on it which have lowercase letters in it (just guessing):

protected static final String GPG_URL_REGEX = "^(https?|file)://.*?$";
