Description

When I build Derby using JDK 10, I get the following warning:

    [javac] /Users/rhillegas/derby/mainline/trunk/java/engine/org/apache/derby/iapi/types/SqlXmlUtil.java:728: warning: [unchecked] getPrefixes(String) in NullNamespaceContext implements getPrefixes(String) in NamespaceContext
    [javac]         public Iterator getPrefixes(String namespaceURI) {
    [javac]                         ^
    [javac]   return type requires unchecked conversion from Iterator to Iterator<String>
    [javac] 1 warning

I will clean this up.
