JFYI- this health check does not perform any HTTP connection and these are just INFO level logs for the health check module so can be ignored. You may suppress the msgs to avoid noises in the logs, in case you don't want to disable the bundle by:
Go to Felix console : "/system/console/configmgr"
Search for Apache Sling Logging Logger Configuration
Click on +icon to create a new logging configuration.
Set Log Level to "WARN" - So that you get relevant warnings ONLY for this class- "org.apache.commons.httpclient.HttpMethodDirector"
Under Loggerenter the classname - org.apache.commons.httpclient.HttpMethodDirector
