Description

In the attached test case, if you quickly tap "Open window" and "close window" over and over again, you will eventually see this debug message in the log:

I/TiAPI   ( 4250): closing window 2
D/Window  ( 4250): unable to close, window is not opened

There isn't an associated stack trace, but it seems the fast open/close is causing the internal state tracking in window.js to be out of sync Here's the code:

//create window 1.
Ti.API.info("opening window 1");
var win = Ti.UI.createWindow({ 
	backgroundColor: "#fff", 
	navBarHidden: true, 
	softInputMode: Ti.UI.Android.SOFT_INPUT_ADJUST_RESIZE, 
	exitOnClose: true 
});
win.open();

var label = Ti.UI.createLabel({ text: "Window 1", width: "auto", height: "auto", top: 10 });
win.add(label);

var openWindow2Button = Ti.UI.createButton({ title: "Open Window 2", height: "auto", width: "auto", bottom: 10 });
openWindow2Button.addEventListener("click", function() { 

	//create window 2.
	Ti.API.info("opening window 2");
	var win2 = Ti.UI.createWindow({ 
		backgroundColor: "#fff",
		navBarHidden: true,//this causes crash on window 2 close!!
		softInputMode: Ti.UI.Android.SOFT_INPUT_ADJUST_RESIZE, 
		exitOnClose: false 
	});
	win2.open();

	var label2 = Ti.UI.createLabel({ text: "Window 2", width: "auto", height: "auto", top: 10 });
	win2.add(label2);
	
	var closeWindow2Button = Ti.UI.createButton({ title: "Close Window 2", height: "auto", width: "auto", bottom: 10 });
	closeWindow2Button.addEventListener("click", function() { 
		Ti.API.info("closing window 2");
		win2.close(); 
	});
	win2.add(closeWindow2Button);

	var table = Ti.UI.createTableView({ top: 60, bottom: 60, left: 0, right: 0, data: [] });
	win2.add(table);
	
});
win.add(openWindow2Button);

I have exactly the same issue, but a simplified test like the following doesn't replicate so the weight of the actually windows being closed must be part of the problem:

   var appWindow = Ti.UI.createWindow({
       backgroundColor: 'red',
       exitOnClose: true,
       modal: false // Force heavyweight
   });
   
   var mainWindow = Ti.UI.createWindow({
       backgroundColor: 'green',
       modal: false // Force heavyweight
   });
   
   mainWindow.addEventListener('click', function () {
       Ti.API.info('Main window tapped, now closing main window');
       mainWindow.close();
   });
   
   mainWindow.addEventListener('close', function () {
       Ti.API.info('Main window closed, now closing app window');
       appWindow.close();
   });
   
   appWindow.addEventListener('open', function () {
       Ti.API.info('App window opened, now opening main window');
       mainWindow.open();
   });
   
   appWindow.open();

Closing ticket as the issue cannot be reproduced and due to the above comments.
