> [JDK-8169880](https://bugs.openjdk.org/browse/JDK-8169880) removed a debugging option to disable caching of reflective data in java.lang.Class, which had a consequence that now Class#reflectiveData method guarantees to return a non-null result. Existing callers of that method were left intact and still contain null checks and branches that are never taken after this change. Some new callers were added later and they don't have null checks. I propose a patch to remove these unneeded null checks and never taken branches.

Good; now no usage of `reflectionData()` involves redundant null checks. Also it's 2025 so you get the privilege to bump copyright year on `Class.java`.
