findbugs: NP_NULL_PARAM_DEREF

NP: Null passed for nonnull parameter of makeURLs(X509V3ExtensionUtil$PathNode,
List, StringBuffer) in
org.candlepin.util.X509V3ExtensionUtil.hydrateContentPackage(byte[])

This method call passes a null value for a nonnull method parameter. Either the
parameter is annotated as a parameter that should always be nonnull, or analysis
has shown that it will always be dereferenced.
findbugs: WMI_WRONG_MAP_ITERATOR

WMI:
org.candlepin.util.X509V3ExtensionUtil.orderStrings(X509V3ExtensionUtil$PathNode)
makes inefficient use of keySet iterator instead of entrySet iterator

This method accesses the value of a Map entry, using a key that was retrieved
from a keySet iterator. It is more efficient to use an iterator on the entrySet
of the map, to avoid the Map.get(key) lookup.
