Since migration to AWS SDK v2 in EC2 plugin (since aws-credentials-plugin 238.v8fb_588a_2b_e67), the non proxy hosts configured in Jenkins global proxy configuration are not taken into account. The proxy is being used when it should not. Typically in environment where we want to bypass the Proxy for AWS connections..

Workaround: set the java system properties -DhttpNonProxyHosts..
