Unable to change perspective using SWTbot and Juno [message #962777]

I have a huge set of test cases developed on Eclipse Indigo whose first constraint is to change the Eclipse perspective. Below is the code for the same.

SWTBotView view = bot.viewByTitle("Welcome");
if (view.isActive()) {
view.close();
}

// Change the perspective via the Open Perspective dialog
bot.menu("Window").menu("Open Perspective").menu("Other...").click();
SWTBotShell shell = bot.shell("Open Perspective");
shell.activate();

However the test case when running on Eclipse Juno (4.2) fails with the following error:

org.eclipse.swtbot.swt.finder.exceptions.WidgetNotFoundException: Could not find widget.
at org.eclipse.swtbot.swt.finder.SWTBotFactory.waitUntilWidgetAppears(SWTBotFactory.java:348)
at org.eclipse.swtbot.swt.finder.SWTBotFactory.menu(SWTBotFactory.java:257)
at org.eclipse.swtbot.swt.finder.SWTBotFactory.menu(SWTBotFactory.java:208)
at org.eclipse.swtbot.swt.finder.SWTBotFactory.menu(SWTBotFactory.java:198)
at ... 41 more

The exact line is while it is trying to access the menu. Do let me know if there is any change i need to make, to make the test case work for Juno.

Thanks in advance.

Guess, this won't make you happy: https://bugs.eclipse.org/bugs/show_bug.cgi?id=385527

How about this: you use the perspective ID? E.g. for opening resource perspective you try :
bot.perspectiveById("org.eclipse.ui.resourcePerspective").activate();
Or a bit nicer:
SWTBotPerspective botPerspective = bot
.perspectiveById("org.eclipse.ui.resourcePerspective");
assertNotNull(botPerspective);
botPerspective.activate();

Which menu?
Is this menu actually here? Eclipse 4.2 has some refactoring in the
Welcome menu IIRC, so maybe you're simply missing the plugin responsible
of displaying it.

Do you use Linux? Do you have a working window manager on the DISPLAY
you're using? I saw some issues like this one before because of usage of
twm or other bad window managers...

This issue with perspectives has not been reported so far. So please
report it as precisely as you can if you think it's a bug because of
Eclipse 4.2.

It's the basic Windows menu that is used to access perspectives as in the case of code below. This menu comes with Eclipse Juno 4.2.
bot.menu("Window")

All the plugins are available.

No, i am Windows user. Also i found hitting this issue again when i tried to create some projects and build using 'Build All' option. I am unable to access the menu 'Project'.
bot.menu("Project").menu("Build All").click();
Even this throws the same WidgetNotFoundException.

Are you sure those menus are actually present in your test environment.
If you start the IDE with the exact same plugins as in tests, but
without running SWTBot, can you see them?
