This method creates an SSLContext based on the default provider and then
created TrustManagers, KeyManagers and initializes the SSLContext with
the TrustManager, KeyManager
This class extends the SSLConfigHolder for the sole purpose of
overriding the logEmptyWarning method, since this method in the super class
assumes that there is a network-config element assocaited with each ssl element
in the domain.xml.
Called when ConfigBeans come into the habitat (see GlassfishConfigBean); a job queue
is maintained for processing by the AMXConfigLoader, which is lazily loaded.
