This patch makes the result of "java -Xshare:dump" deterministic: - Disabled new Java threads from launching. This is harmless. See comments in jvm.cpp - Fixed a problem in hashtable ordering in heapShared.cpp - BasicHashtableEntry has a gap on 64-bit platforms that may contain random bits. Added code to zero it. - Enabled checking of $JAVA_HOME/lib/server/classes.jsa in make/scripts/compare.sh
Note: $JAVA_HOME/lib/server/classes_ncoops.jsa is still non-deterministic. This will be fixed in [JDK-8282828](https://bugs.openjdk.java.net/browse/JDK-8282828). Testing under way: - tier1~tier5 - Run all *-cmp-baseline jobs 20 times each (linux-aarch64-cmp-baseline, windows-x86-cmp-baseline, .... etc). ------------- Commit messages: - Merge branch 'master' into 8253495-cds-generateds-non-deterministic-output-2 - fixed test - more fixes - 8253495: CDS generates non-deterministic output Changes: https://git.openjdk.java.net/jdk/pull/7748/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=7748&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8253495 Stats: 73 lines in 12 files changed: 49 ins; 7 del; 17 mod Patch: https://git.openjdk.java.net/jdk/pull/7748.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/7748/head:pull/7748 PR: https://git.openjdk.java.net/jdk/pull/7748
