Air 3.9 for iOS - Increased file size of the executable?

Hi,

I've just exported a new release of my app with the new Air 3.9 SDK.

I've discovered that the file size of the .ipa is increased of 9MB (before it was 30, now it's 39...)

Looking into the Payload, I've found that the exutable itself is increased from 7 MB to 30 MB...

Is that possibile? Or am I doing something wrong?

I'm on FLEX SDK,

This is the adt command line (part of it):

adt

    -package

    -target

    ipa-app-store

    -hideAneLibSymbols

    yes

    -storetype

    pkcs12

This is the compiler arguments:

-target-player=11.9

+configname=airmobile

-library-path+="{flexSDK}/frameworks/locale/en_US"

-default-size=550,400

-locale=en_US,fr_FR,it_IT -source-path=locale/{locale}

-swf-version=22 -allow-source-path-overlap=true

-optimize=true

Thanks

Andrea
