5005: Unknown error optimizing byte code

[Guest]

During routine build and testing, I start getting an error 5005: "Unknown error optimizing byte code" when I try to build my main .fla, even if there were no changes to the .fla or any of its associated files.

After closing Flash, starting it up again, and then reopening the project, everything works.

Has anyone else seen this?

More info on this: it doesn't appear to happen with any regularity. Some sessions I go for many rebuilds before it crops up, other sessions it happens on the very first try. In every case, if I just restart Flash and reload the project and try again, it builds fine.

I am also getting this error. I tried turning off the optimizer for the AS3 compiler but this did not resolve the issue. Have you had any luck finding a solution to this? One other thing I heard was that this problem might be from an application originally built in the Flash 9:blaze alpha from Adobe labs site. Was your application built in the alpha release of Flash?
Thanks,
Sean

I've posted an article on this problem - http://www.negush.net/blog/5005-unknown-error-optimizing-byte-code/ - and here are a few ideas on how to handle it (check out the comments):
- try turning off the optimizer
- delete ASO files
- also it seems that changing the java vm heap memory size could help (find he environment variables in the Windows computer properties and search the JAVA_TOOL_OPTIONS variable)
