When java is installed as a package endpoint, the name of the folder that it is installed into will mirror the ID you use. This means two different installation IDs that resolve to the exact same Java version may end up in different folders. We do this for a couple reasons. One of which is simplicity, the other is that if you have configuration expecting a specific folder name, Mac users and Windows users may get a different download, but if the id is simple java:openjdk8_jdk
, they would both install into a folder called openjdk8_jdk
.
