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.
