I did a 6 to 8 migration at $lastjob. The upgrade was smooth except for 2 issues: * It exposed a kernel panic bug in our Linux kernel when Hadoop applications de-allocated huge amounts of RAM at once (e.g. a Spark program with a 100GB heap exiting suddenly would panic the system) * It introduced a weird UI behavior change in Swing in one of our desktop apps. In fairness, whoever wrote the app first did some weird unnecessary shit with JComboBoxes, but it was still somewhat odd to me that the behavior changed. The bug was like, when previously if you clicked a box it'd swap it out for a JComboBox that had the previous content of the non-combobox-view-thingy that was in its place. On 8, for some reason it would always be blank and discard the old content. Don't quote me on this description, though. It was a while ago and it was a weird interaction regardless. So, idk. It's always something. Software, eh? |
