In GlassApplication.m for iOS, the method
Java_com_sun_glass_ui_ios_IosApplication__1leaveNestedEventLoopImpl has signature (Ljava/lang/Object;)V.

However, in IosApplication.java, _leaveNestedEventLoop(Object retValue) receives an object, but it doesn't pass it to _leaveNestedEventLoopImpl() as it should.

In other words, _leaveNestedEventLoopImpl() has wrong signature.
