Problem Description: Recently a hacker threw an invalid returnformat into Ajax calls to a remote CF method. This produced errors that we do not seem to be able to catch and handle via normal methods. 

Steps to Reproduce: Call remote method with a returnFormat that is not in the allowed list. 

Any Workarounds: Since we aren't able to catch this error, we've had to use the global error handler to recognize and work around it.

As I mentioned in the Description to reproduce, just hit a remote CFC (via Ajax) with a remoteFormat that is not valid. The one we get hit with seems to always be "jsPr". As a result, this is the error that gets thrown: coldfusion.filter.FilterUtils$InvalidReturnFormatException: Invalid returnFormat: jsPr. at coldfusion.filter.FilterUtils.printReturnValue(FilterUtils.java:262) at coldfusion.filter.ComponentFilter.invoke(ComponentFilter.java:202) ETC.... MESSAGE: Invalid returnFormat: jsPr. DIAGNOSTICS: Invalid returnFormat: jsPr. The returnFormat request parameter must be specified as wddx, json or plain. The error occurred on line -1.

The serializarion based on the rerurnformat is being handle by ColdFusion core engine and does not fall under Applicationcode. Hence there is no other way than global handler to handle this. If a wrong returnformat is really an issue then, you can pre-check it in the function (url.returnformat EQ jsPr) and take the appropriate action.
