Yes agreed. Those macros are a bit dangerous. Recently, when I looked into [JDK-8297274](https://bugs.openjdk.org/browse/JDK-8297274?focusedCommentId=14540238&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14540238url) there was another oddity that stood out. Reading values in as `julong` and then casting them to `jlong` :-/
