Thanks for your reply, Owen. > That said, I’d be surprised if the work items for JDK 9 and 10 aren’t a strict subset of the issues getting to JDK 11.
Most of the issues that we have fixed are subset of the ones of JDK 11. But there seem to be some exceptions. HADOOP-15905 is a bug of JDK 9/10 which has been fixed in JDK 11. It is difficult to fix it since JDK 9/10 have already been EOL. I wonder if we should treat such a kind of error going forward. > I've hit at least one pretty serious JVM bug in JDK 11 Could you please share that detail? In any case, we should be carefully that what version of Hadoop is ready for JDK 11. It will take some time yet. And we also need to keep supporting JDK 8 for a while.
