Hi all, Michael contributed a patch that works around the 4k limit. Unfortunately it is not only a modification of the existing PlatformOracleImpl but has some deeper impact on the codebase. So I did not apply his patch one to one to the codebase. I planned to have a complete walkthrough of his solution in december. But as many other things it got delayed...
Michael, maybe this is a good timing for a relaunch of your solution. Please repost it so that more people get an impression!
