Fix request (13u): on behalf of Ekaterina Vergizova (katya@azul.com) I'd like to backport it to 13u as well. The original patch was amended, see https://mail.openjdk.java.net/pipermail/jdk-updates-dev/2020-June/003298.html

Fix request (11u): Requesting backport of this test fix for Oracle 11.0.7 parity. Patch applies cleanly but does not work. It had to be amended. RFR mail was sent out: https://mail.openjdk.java.net/pipermail/jdk-updates-dev/2020-March/002782.html

The mapping failures shouldn't on 14 anymore, due to JDK-8231610 (Relocate the CDS archive if it cannot be mapped to the requested address).

The test scenario using the UseAppCDS option was removed in JDK12 via the fix for JDK-8204591: Expire/remove the UseAppCDS option in JDK 12. Other test scenarios could fail in the same way. A potential patch to handle archive mapping failure is as follows: bash-4.2$ hg diff CommandLineFlagComboNegative.java diff --git a/test/hotspot/jtreg/runtime/cds/appcds/CommandLineFlagComboNegative.java b/test/hotspot/jtreg/runtime/cds/appcds/CommandLineFlagComboNegative.java --- a/test/hotspot/jtreg/runtime/cds/appcds/CommandLineFlagComboNegative.java +++ b/test/hotspot/jtreg/runtime/cds/appcds/CommandLineFlagComboNegative.java @@ -86,9 +86,14 @@ TestCommon.checkDump(dumpOutput, "Loading classes to share"); - OutputAnalyzer execOutput = TestCommon.exec(appJar, testEntry.testOptionForExecuteStep, "Hello"); - execOutput.shouldContain(testEntry.expectedErrorMsg); - execOutput.shouldHaveExitValue(testEntry.expectedErrorCode); + TestCommon.run( + "-cp", appJar, + testEntry.testOptionForExecuteStep, + "Hello") + .assertAbnormalExit(output -> { + output.shouldContain(testEntry.expectedErrorMsg) + .shouldHaveExitValue(testEntry.expectedErrorCode); + }); } }

According to the log, below is the reason for the failure and not due to the mismatch of ObjectAlignmentInBytes as indicated in the title of this bug. ----------System.err:(24/1279)---------- stdout: [Error occurred during initialization of VM Unable to use shared archive. ]; stderr: [Java HotSpot(TM) 64-Bit Server VM warning: Ignoring obsolete option UseAppCDS; AppCDS is automatically enabled An error has occurred while processing the shared archive file.
