Depending on which version & configuration of CF/Railo you're using the issue is that we shouldn't have really used the variable name "url". This can easily be fixed by updating the below two functions noting the variable name has been changed to uri...
<cffunction name="isWrapped" access="private" returntype="boolean" output="true">
<cfargument name="uri" type="string" required="true" />
<cfif find("FusionReactor", uri)><cfreturn true><cfelse> <cfreturn false></cfif>
</cffunction>
<cffunction name="getWrappedString" access="private" returntype="string" output="true">
<cfargument name="uri" type="string" required="true" />
<cfif find("FusionReactor", uri)><cfreturn "<font color='green'><b> wrapped</b></font>"><cfelse> <cfreturn "<font color='red'><b>unwrapped</b></font>"></cfif>
</cffunction>
