Damian Hagge commented on CB-2812:
----------------------------------
I've isolated this issue to our upgrade from phonegap 2.1 to phonegap 2.3 - the
same code worked previous to our upgrade and was broken after the upgrade. I
suspect that some change in the way in which the UIWebView is being
launched/rendered is causing this issue to occur.
Also if you see the post on
https://groups.google.com/forum/?fromgroups=#!msg/phonegap/oDOAwKjmpRQ/QfcWp9B3h5sJ
others are seeing this same behavior with that upgrade.
As a side note: interestingly if you do a jsfiddle on iPhone safari and
alert(window.navigator.javaEnabled()) it returns false (i.e. does not return
TypeError).

> After upgrading to cordova 2.5.0 calls to navigator.javaEnabled() raise

> It's possible that this issue may exist in previous versions back to 2.2.0

> however it definitely does exist in 2.5.0.
> Raised with priority critical since it's a straight up API break.
