<cfcatch> not 'catching' an error

Question

I've got an image processing CFC to handle uploaded images. In the method, I'm creating an new image of the uploaded file with ImageNew() and then resizing it if needed (along with some other validation to make sure it's an image). Here's a snippet of the code:

<cftry>
        <cfset ImageScaleToFit(#local.uploadedImage#, 72, "", "highestPerformance")>
        <cfimage action="write" source="#local.uploadedImage#" destination="#local.newThumbName#" overwrite="yes" >
        <cfcatch type="any">
            <cfset local.response['catcher'] = #cfcatch.Detail#>
            <cfset local.response['success'] = false>
            <cfreturn local.response>
        </cfcatch>
    </cftry>

After I upoloaded the code to the production server it began throwing an error because "highestPerformance" isn't an available option for image compression on the production server.

As a backup for <cftry> exception handling I have the Application.cfc send me an email of the details while masking the errors from the user in the event the 'try' doesn't cathc the error.

Throughout the CFC the <cftry> catches the error and sends it back to my page. where it gets output to the console.

My question is, why does this particular block of code not work with <cftry> and the error gets sent directly to the exception handling in my Application.CFC?

Is there some sort of "error threshold" that my built-in exception handling can't handle?

BTW, "highPerformance" works for some reason even though the documentation at Adobe says "highestPerformance" is an available option...

EDIT:

Here's the error I'm getting from the Application.cfc

Could not initialize class javax.media.jai.JAI

And the stack trace:

Answer 1

The catch fails because the call to ImageScaleToFit() crashes the JVM. It sounds like your production sever is either missing the Java Advanced Imaging API (javax.media.jai.JAI) or it is not included in the classpath.

Answer 2

If you are using ColdFusion 8 make sure that you have all hotfixes and updates applied. CF 8 had a lot of major issues with image functions and tags, and if Java is causing the error underneath CF might not be able to catch it. Even if you aren't on CF 8 make sure that everything is updated.
