By adding an `InstanceKlass* InstanceKlass::super()` method to shadow `Klass* Klass:super()`, this PR makes it possible to simplify the following code
InstanceKlass* ik; InstanceKlass* s; s = InstanceKlass::cast(ik->super()); // before JDK-8366024 s = ik->java_super(); // after JDK-8366024 to s = k->super(); So you no longer need to do casting or need to understand what `java_super()` is. ------------- Commit messages: - 8366584: Add an InstanceKlass::super() method that returns InstanceKlass* Changes: https://git.openjdk.org/jdk/pull/27037/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=27037&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8366584 Stats: 91 lines in 28 files changed: 8 ins; 2 del; 81 mod Patch: https://git.openjdk.org/jdk/pull/27037.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/27037/head:pull/27037 PR: https://git.openjdk.org/jdk/pull/27037
