Temurin-build: java.vendor.version only displays "AdoptOpenJDK"

[brunoborges]

The System property java.vendor.version should provide better pointer to the source code version used by AdoptOpenJDK to build OpenJDK. Currently, it only says AdoptOpenJDK.

[lumpfish]

For information, these are the current property settings for jdk11 (hotspot and openj9):

hotspot:
    java.vendor = AdoptOpenJDK
    java.vendor.url = https://adoptopenjdk.net/
    java.vendor.url.bug = https://github.com/AdoptOpenJDK/openjdk-build/issues
    java.vendor.version = AdoptOpenJDK
    java.version = 11.0.5
    java.version.date = 2019-10-15
    java.vm.compressedOopsMode = Zero based
    java.vm.info = mixed mode
    java.vm.name = OpenJDK 64-Bit Server VM
    java.vm.specification.name = Java Virtual Machine Specification
    java.vm.specification.vendor = Oracle Corporation
    java.vm.specification.version = 11
    java.vm.vendor = AdoptOpenJDK
    java.vm.version = 11.0.5+10

openj9:
    java.vendor = Eclipse OpenJ9
    java.vendor.url = http://www.eclipse.org/openj9
    java.vendor.version = AdoptOpenJDK
    java.version = 11.0.5
    java.version.date = 2019-10-15
    java.vm.info = JRE 11 Windows 10 amd64-64-Bit Compressed References 20191016_357 (JIT enabled, AOT enabled)
OpenJ9   - 77c1cf708
OMR      - 20db4fbc
JCL      - 2a7af5674b based on jdk-11.0.5+10
    java.vm.name = Eclipse OpenJ9 VM
    java.vm.specification.name = Java Virtual Machine Specification
    java.vm.specification.vendor = Oracle Corporation
    java.vm.specification.version = 11
    java.vm.vendor = Eclipse OpenJ9
    java.vm.version = openj9-0.17.0
    jdk.extensions.name = Extensions for OpenJDK for Eclipse OpenJ9
    jdk.extensions.version = 11.0.5.0

Since AdoptOpenJDK has the notion of the 'build suffix', perhaps this property would be a place to capture that information (e.g. 11.0.4+11.4)?

@lumpfish Did we have any discussions on what the values of this should be?

[M-Davies]

ping @lumpfish ref https://github.com/AdoptOpenJDK/openjdk-build/issues/1387#issuecomment-593980424

[lumpfish]

No discussions I'm aware of.

~This has been changed in #2073 to default to the variant being built.~

This is being reverted.

It may be useful to look at what other distros set this property as for a start.

[andrew-m-leonard]

java.vendor.version = Zulu16.28+11-CA
java.vendor.version = Corretto-11.0.10.9.1

Bell Soft Liberica doesn't have it (couldn't find it on the Mac, at least)

java.vendor.version is optional, openjdk wanted to remove it at one point: https://bugs.openjdk.java.net/browse/JDK-8216383

[andrew-m-leonard]

I quite like using our metadata version string:
"version": "11.0.11+7-202103181819"
and stick AdoptOpenJDK on the front, so:
“AdoptOpenJDK-11.0.11+7-202103181819”
for a nightly build

A release would be:
"AdoptOpenJDK-16+36"

[andrew-m-leonard]

@smlambert just one thought going forward, what's the position on the word AdoptOpenJDK vs EclipseAdoptium ?

[smlambert]

Once we complete our transition to Eclipse Foundation and produce our first release (TCKed) under their banner, those properties (and certs we use, etc) will get updated, java.vendor = Eclipse, etc., so you could plan to create this metadata version string where java.vendor.version = java.vendor + version

[andrew-m-leonard]

Example here:

    java.vendor.version = AdoptOpenJDK-11.0.11+7-202103230931

openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment AdoptOpenJDK-11.0.11+7-202103230931 (build 11.0.11+7-202103230931)
OpenJDK 64-Bit Server VM AdoptOpenJDK-11.0.11+7-202103230931 (build 11.0.11+7-202103230931, mixed mode)

[andrew-m-leonard]

    java.vendor.version = AdoptOpenJDK-16+36

openjdk version "16" 2021-03-16
OpenJDK Runtime Environment AdoptOpenJDK-16+36 (build 16+36)
OpenJDK 64-Bit Server VM AdoptOpenJDK-16+36 (build 16+36, mixed mode, sharing)
