tracker issue : CF-3925916

Problem Description:  cfspreadsheet tag is unable to write to the Virtual File System by using "ram://"

This was reportedly fixed in CF 10 Update 11, and previously reported in these Bugs:
3178676 "cfspreadsheet with ram://"
3042909 "Cannot use action="write" with the cfspreadsheet tag and a filename on the VFS "

Steps to Reproduce:
<cfoutput>
	<br><br>Write text file to disk
	<cffile action="write" file="#expandPath('./cfspreadsheet.txt')#" output="Quick Test">

	<br><br>Write text file to ram
	<cffile action="write" file="ram://cfspreadsheet.txt" output="Quick Test">

	<br><br>Read text file from ram
	<cffile action="read" file="ram://cfspreadsheet.txt" variable="ReadInfo">

	<br><br>We read in: #ReadInfo#
	
	<cfset qtest = QueryNew('A,B,C')>
	<br><br>Write excel file to disk	
	<cfspreadsheet action="write" filename="#expandPath('./cfspreadsheet.xls')#"query="qtest" overwrite="true"> 
	<br><br>Write excel file to ram
	<cfspreadsheet action="write" filename="ram://cfspreadsheet.xls" query="qtest" overwrite="true"> 
	<!--- The above line throws an error --->
</cfoutput>

Actual Result:  The following error message is displayed:
An exception occurred while using action=write.  
java.io.FileNotFoundException: ram:///cfspreadsheet.xls  


Expected Result:  cfspreadsheet should write the excel file to ram and not throw an error.

Any Workarounds:  Write to Disk instead of ram.

Other:
In the example above I write to and read from ram using cffile just to verify that ram:// is available.  All of the code above worked except for the last line trying to cfspreadsheet to ram://.

I don't have the ability to remove updates from the ColdFusion server so I have no way to test which update broke this functionality, or if it was still broke after Update 11.  I'm only now trying to use this to help with the god awful slowness of the spreadsheet functions in ColdFusion.
