The fix is for a regression caused by: [8308614](https://bugs.openjdk.org/browse/JDK-8308614) Enabling JVMTI ClassLoad event slows down vthread creation by factor 10
The fix of 8308614 just triggered a known issue: [8316283](https://bugs.openjdk.org/browse/JDK-8316283) field watch events are not always posted with -Xcomp option The fix is just a work around with the extra checks of the `JvmtiExport::should_post_field_access()` and `JvmtiExport::should_post_field_modification()`.
