Flex 4.1 SDK compilation error=3

Question

I just downloaded SDK 4.1 and tried to compile my application but I'm getting the following error:
C:\projects\MyProject\build.xml:119:Execute failed: java.io.IOException:CreateProcess: "C:\Program Files\Adobe\Adobe Flash Builder Plug-in Beta 2\sdks\4.1\bin\mxmlc.exe" -strict=true -show-actionscript-warnings=true -keep-generated-actionscript=false -use-network=true -target-player=10.0.0 -source-path=C:\projects\MyProject-Flex/ui/trunk/src -library-path+=C:\projects\MyProject -Flex/ui/trunk/libs -output=C:\apache-tomcat-5.5.25/webapps/MyProject/Main.swf C:\projects\MyProject-Flex/ui/trunk/src/Main.mxml error=3
Line 119 in build.xml is the starting of the following:
        <exec executable="${FLEX_HOME}/bin/mxmlc.exe">
            <arg line="-strict=true" />
            <arg line="-show-actionscript-warnings=true" />
            <arg line="-keep-generated-actionscript=false" />
            <arg line="-use-network=true" />
            <arg line="-target-player=10.0.0" />
            <arg line="-source-path=${sourceDirUI}" />
            <arg line="-library-path+=${FLEX_BASE_DIR}/ui/trunk/libs" />
            <arg line="-output=${webDirUI}/Main.swf" />
            <arg line="${sourceDirUI}/Main.mxml" />
        </exec>
Any idea what's going on and what error=3 stands for?
The same ant build.xml has been working with sdk 4.1.0.15735
Thanks.

@Jason Villmer,
I believe the issue you're describing is http://bugs.adobe.com/jira/browse/SDK-26940.
There is a workaround listed in the bug report which should work (based on my testing), or you could probably set the direction and layoutDirection styles globally using a Style block.
