Please refer to the "Intellij Idea" section on the ide doc: https://github.com/openjdk/jdk/blob/master/doc/ide.md#intellij-idea In short, in `jdk`, you need to run the `bin/idea.sh` with cygwin after you've done `make images` once. Then the root `jdk` directory will be recognized by idea as an idea project.
Note that the guide asks to set the SDK to your images/jdk in the project. Due to problems within Intellij, you should unset the JDK, so the files won't show up a "package xxx already exists in java.base" error. You should set the language level to `X-Experimental features` to mute the warnings about some API usages. And then, you can navigate JDK code as in any other project, such as double-shift and search `Stream` to find the `java.util.stream.Stream` class. And once you are there, you may encounter the bug I've described, that actually used methods will appear as "unused": you will have to type something in one of the method names, like change `filter` to `filter1` so Intellij idea does a reindex and you can find usages of other methods/overrides of the interface.
