OOM error using FB 4

Question

Hi, getting OOM error when doing a build of a project using
flash builder 4 standalone (on windows 7, 64bit).
I've tried all manner of increasing the heap size. Below is the stack trace from the log file (in .metadata/.log). One thing i did notice is the java.version. This jre is not one i have installed, so it must be the one which is installed with the product (in FLEX_HOME/jre). Now, how does one control the vmargs for this invocation? I tried messing with FlashBuilder.ini, as well as jvm.config in the sdks directories; to no avail.

Just to simplify, I created another mobile project in 4.5 prerelease, this one is a  "supported" ActionScript only project, with the same results.  The code for the entire iphone project is below.  I'm including lccsFlash.swc (10.1 version).  Image of the result on the phone is attached (same as before).
The code is here:
private var debugtext:String;
private var auth:AdobeHSAuthenticator;
private var txtfld:TextField = new TextField();
private function myLccsTrace(debugStr:String):void{debugtext += debugStr +
"\n";txtfld.text = debugtext;
private function updateDebug(event:Event):void{txtfld.text = debugtext;
public function ActionScriptMobile(){
super();  
// support autoOrientsstage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
startConnect();
 private function startConnect():void{DebugUtil.traceFunction = myLccsTrace;
DebugUtil.suppressDebugTraces=
false;debugtext +=
"Starting viewactivatehandler... \n";
debugtext +=
"Creating auth \n";auth =
new AdobeHSAuthenticator();auth.userName =
"Guest";auth.requireRTMFP=
false;
cSession =
new ConnectSession();debugtext +=
"Created ConnectSession \n";cSession.authenticator = auth;
cSession.roomURL=
http://collaboration.adobelivecycle.com/MYACCT/MYROOM;cSession.addEventListener(SessionEvent.SYNCHRONIZATION_CHANGE, updateDebug);
debugtext +=
"Trying login... \n";cSession.login();
debugtext +=
"After login \n";
txtfld.width=800;
txtfld.height=1200;
txtfld.text = debugtext;
this.addChild(txtfld)  }
Same error as before.  Also, the "guk=" is from the LCCS code after the login(), I'm not adding any additional parameters, all the code is above.
