AirPrintANE is not displaying print dialog on iOS 8.x but works on 7.x and 6.x

I use janumedia AirPrintANE native extension to print from AIR app from iPad. After the February 2015 requirements to compile 64bit binary and for ANEs to support universal libraries I compiled AirPrintANE in xcode using appropriate architecture (arm64, armv7, armv7s). Now it builds and works fine on iOS 6.x and 7.x but does not show the print dialog on 8.x version of iOS. I'm not very confident on objective-c side of this ANE so can anyone more confident suppose what is going on there?
