proposed fix

Hello,

We have had a report of systematic java startup crashes:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=824226#22

Investigation has shown that in his environment, the accessibility bus 
does not work for some reason. But that should not make Java applications 
crash. It happens that java-atk-wrapper does not really check that the 
at-spi initialization really went fine (or was disabled). When later 
java-atk-wrapper calls at-spi functions, horrible things can happen.

In the patch proposed here, java-atk-wrapper is simply made to check the value returned by atk_bridge_adaptor_init, to watch for at-spi initialization failures, and in that case avoid setting up hooks etc.

Samuel
