Following jtreg tests for SA would fail because SA has not followed [JDK-8220587](https://bugs.openjdk.java.net/browse/JDK-8220587) and [JDK-8224965](https://bugs.openjdk.java.net/browse/JDK-8224965).
* serviceability/sa/ClhsdbDumpheap.java * serviceability/sa/ClhsdbFindPC.java * serviceability/sa/ClhsdbInspect.java * serviceability/sa/ClhsdbSymbol.java * serviceability/sa/TestHeapDumpForInvokeDynamic.java * serviceability/sa/TestJmapCore.java * serviceability/sa/TestJmapCoreMetaspace.java They need to handle relocated objects and/or live regions (pages). SA should handle them. This change passes serviceability/sa jtreg tests on Linux x64 with -vmoption:-XX:+UseZGC, but I want to know this change works fine on testbed for ZGC in Oracle. Could you help? ------------- Commit messages: - Improve relocation handling - Merge remote-tracking branch 'upstream/master' into JDK-8266957 - 8266957: SA has not followed JDK-8220587 and JDK-8224965 Changes: https://git.openjdk.java.net/jdk/pull/4057/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=4057&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8266957 Stats: 799 lines in 23 files changed: 558 ins; 191 del; 50 mod Patch: https://git.openjdk.java.net/jdk/pull/4057.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/4057/head:pull/4057 PR: https://git.openjdk.java.net/jdk/pull/4057
