Additional info:
Recreated this in my devenv.  I experienced this failure only for cdi-api-1.0-SP4.jar.  Interestingly, when I download the POM and compute the checksum manually (sha1sum cdi-api-1.0-SP4.pom), it matches the checksum present on the server.
It looks to me like the problem here is a bad redirect to HTTPS when fetching the checksum:
$ curl -v --insecure http://mirror1.ops.rhcloud.com/nexus/content/groups/public/javax/enterprise/cdi-api/1.0-SP4/cdi-api-1.0-SP4.pom.sha1

OK, fixed.  This was my fault.
An http configuration change I made yesterday redirected any http requests with /enterprise/ in their path to https requests.
I have fixed the configuration and this should be working again.
I apologize for this misconfiguration.
