WTF? – 5005: Unknown error optimizing byte code.
I recently came across a problem I hadn’t had before – 5005: Unknown error optimizing byte code.
After a little googling I found that this occurs when you are compiling a large project (e.g a lot of code) from the Flash IDE. Now I don’t tend to compile these sort of projects from the Flash IDE (usually I’d compile it straight from FDT or FlashBuilder), but for various reasons this project required it.
So, after reading this blog post, I found it was simply a matter of increasing the memory allocated to the Flash IDE.
If you’re on a mac, head over to /Users/YOUR_USER_NAME/Library/Application Support/Adobe/Flash CS5/YOUR_LANGUAGE/Configuration/ActionScript 3.0/ and open jvm.ini in your favourite text editor. Then increase -Xmx128m to -Xmx256m (or whatever amount you require), save the file, and you should be good to go.
Make sure you quit Flash before you do this – your changes should come into effect once you relaunch the Flash IDE.

@Kyle – Ha, I’m fine where I am mate!
I’ve actually heard of a few PC users who have had this issue too – it’s just stored somewhere else: System Hard Disk\Users\\AppData\Local\Adobe\Flash CS5\\Configuration\ActionScript 3.0\jvm.ini

This is the first post I found, after searching for three days, that offered a way to resolve this on the Mac. I couldn’t find the file in my Library but I did a spotlight search for “jvm.ini” and found it in “Applications/CS5/Adobe Flash CS5/Common/First Run/Actionscript 3.0/”
Thanks for the clue!
