      Description

        Due to a known issue with the fix for JDK-8155635, introduced in JDK 8 update 202, some applications may experience a performance regression (lower throughput and/or higher CPU consumption) when migrating from earlier releases. Examples of code that might trigger this regression include heavy use of `sun.misc.Unsafe` and the Reflection API. This performance regression is addressed in JDK-8221355.
