Iterating over an Enumeration with CFMX

I tried writing some CFML code to iterate over a java.util.Enumeration, a fairly common thing to do in java, but was plagued with java.lang.IllegalAccessException's.

IllegalAccess exceptions usually occurr when you try to call a method using reflection (which CFMX does) that doesn't exist. However I'm quite sure that hasMoreElements() is a method of java.util.Enumeration. In fact if I cfdump the propNames variable the hasMoreElements method shows up! Here's the code I'm using:

<cfset system = CreateObject("java", "java.lang.System")>
<!--- properties is a java.util.Properties object --->
<cfset properties = system.getProperties()>

<!--- propNames is a java.util.Enumeration --->
<cfset propNames = properties.propertyNames()>

<cfoutput>
 <cfloop condition="propNames.hasMoreElements()">
	<cfset propName = propNames.nextElement()>
	#propName# = #system.getProperty(propName)#<br />
 </cfloop>
</cfoutput>

I suspect the problem has something to do with CFMX not realizing that propNames is an Enumeration, I wish that JavaCast accepted more types besides the primitives.

Here's the stack trace I'm receiving, I'm using CFMX U3:

I may end up reporting this one to Macromedia as a bug, unless I'm missing something here.
