Hey all;

I have been looking at Qt on Android.
Particularly at Qt 5.2,  and I noticed that there are massive numbers of
exceptions
 within the java wrapper for the accessibility ..

e.g.
W/Qt A11y ( 5179): EXCEPTION in dispatchHoverEvent for Accessibility:
java.lang.reflect.InvocationTargetException
W/dalvikvm( 5179): Stack overflow on call to interp (req=76 top=0x4008d000
cur=0x40087328 size=24576 Ljava/lang/reflect/Method;.<init>)
W/Qt A11y ( 5179): EXCEPTION in dispatchHoverEvent for Accessibility:
java.lang.reflect.InvocationTargetException
W/dalvikvm( 5179): Stack overflow on call to interp (req=76 top=0x4008d000
cur=0x40087328 size=24576 Ljava/lang/reflect/Method;.<init>)
W/Qt A11y ( 5179): EXCEPTION in dispatchHoverEvent for Accessibility:
java.lang.reflect.InvocationTargetException
W/dalvikvm( 5179): Stack overflow on call to interp (req=76 top=0x4008d000
cur=0x40087328 size=24576 Ljava/lang/reflect/Method;.<init>)
W/Qt A11y ( 5179): EXCEPTION in dispatchHoverEvent for Accessibility:
java.lang.reflect.InvocationTargetException
W/dalvikvm( 5179): Stack overflow on call to interp (req=76 top=0x4008d000
cur=0x40087328 size=24576 Ljava/lang/reflect/Method;.<init>)
W/Qt A11y ( 5179): EXCEPTION in dispatchHoverEvent for Accessibility:
java.lang.reflect.InvocationTargetException

These occuring whenever the mouse is moved.
Qt Libraries used --  Qt 5.2-beta, and most nightly builds of Qt5.2 rc1 up
to 157.
Latest SDK and NDK
Code used to reproduce - the default app created by the qtcreator wizard
for a QWidget based app.

I know the Accessibility material got added for 5.2 -- thus explaining why
it's not seen when using Qt 5.1.1

Is there an easy way to turn it off  without needed a complete Qt Library
rebuild?

Thanks

Darren
