Changes in aarch64-shenandoah-jdk8u222-b02:
  - S8134030: test/serviceability/dcmd/gc/HeapDumpTest fails to verify
the dump
  - S8151539: Remove duplicate AlwaysTrueClosures
  - S8176100: [AArch64] [REDO][REDO] G1 Needs pre barrier on dereference
of weak JNI handles
  - S8176100: [REDO][REDO] G1 Needs pre barrier on dereference of weak
JNI handles
  - S8210416: [linux] Poor StrictMath performance due to non-optimized
compilation
  - S8217315: Proper units should print more significant digits
  - S8218674: HTML Tooltip with "img=src" on component doesn't show

Main issues of note:

The one to watch out for is JDK-8176100 and the changes to
src/share/vm/runtime/jniHandles.hpp in particular. In addition to having
to backport the AArch64 part of this from OpenJDK 9,
JNIHandles::guard_value was altered to continue the use of
oopDesc:equals and oopDesc:unsafe_equals used in the deleted parts of
resolve_external_guard and resolve_non_null.
