tracker issue : CF-3038576

Problem:

I have a CFC with the following function defined:

	<cffunction name="saveItem" output="false" access="remote" returntype="Product" >
		<cfargument name="item" type="Product" required="true" />
		
		<cfreturn EntitySave( item ) />
	</cffunction>

When I try to use this function, I get an unfriendly error message:

Error Occurred While Processing Request
cannot cast void to non-void 

The error doesn't describe the page that the error occured on.  Rather, the error is just a java stack trace with an IllegalArgumentException.  It took me awhile to figure out where the error actually was.

It would be better if a regular CF error was displayed saying the template and line number of the error, since trying to track down just the java stack trace dump was time consuming.
Method:

a.cfm:
<cfset a = createobject("c1")>
<cfset a.method1()>

c1.cfc:
<cfcomponent>
	<cffunction name="method1" returntype="product">
		<cfoutput>In Method1!!!!</cfoutput>
		<cfreturn EntitySave("c1")>
	</cffunction>
</cfcomponent>

Run a.cfm
Result:

java.lang.IllegalArgumentException: cannot cast void to non-void
