Yes, it sounds like the method cache_simulate_memory_warning_event was never public (at least I couldn’t find any documentation about it) and Apple started to enforce its removal. As far as I can tell, a user of JavaFX web cannot fix this and has currently no chance of publishing a (new?) app to Apples App Store.
For a bit of context, this call is inside the method MemoryPressureHandler::platformReleaseMemory which is implemented differently on different platforms: - cocoa (Mac): with the discussed method - generic: does nothing (empty implementation) - unix: calls `malloc_trim(0);` - win: does nothing (empty implementation) The currently only solution is the one of Michael Hall to add a compiler directive similar to one which was there before 2016-12-14 and no-oped it for certain platforms/versions. I guess this idea would fix the problem of submitting it to Apples App Store.
