I was helping students set up and run Hadoop on Windows machines, and to my surprise, RunJar was pretty much DOA on Windows. This is a pretty standard setup with OpenJDK 11, Windows 11, and Hadoop 3.4.1. I filed HADOOP-19488 <https://issues.apache.org/jira/browse/HADOOP-19488>, and I suspect it was broken by HADOOP-19031 <https://issues.apache.org/jira/browse/HADOOP-19031>. Since HADOOP-19031 was merged into 3.4.0, it means that RunJar has been broken on Windows for nearly a year. Can this be true? Am I off base?
