@bharathappali Can you please investigate the OpenJ9 SCC PR check failures and update your findings here

I have tried to build alpine and ubuntu images of jdk 8 release and figured out that the OpenJ9 slim images are facing the issue of Selected VM [default] does not exist. after running the slim script

Before running slim script:

bharathappali@bharathappali-T590:~/Documents/workstation/git-clones/testspace/openjdk$ ./bin/java -version
openjdk version "1.8.0_292"
OpenJDK Runtime Environment (build 1.8.0_292-b10)
Eclipse OpenJ9 VM (build openj9-0.26.0, JRE 1.8.0 Linux amd64-64-Bit Compressed References 20210421_1000 (JIT enabled, AOT enabled)
OpenJ9   - b4cc246d9
OMR      - 162e6f729
JCL      - 2a5e268814 based on jdk8u292-b10)

After running slim script:

bharathappali@bharathappali-T590:~/Documents/workstation/git-clones/testspace/openjdk$ ./bin/java -version
Selected VM [default] does not exist.
This JVM package includes both the '-Xcompressedrefs' and the '-Xnocompressedrefs' configurations, however the VM directory could not be found. Please download the latest JVM package or build with the most recent changes and run the JVM again.

I feel the issue is we are stripping of something important from the OpenJ9 package.

It appears the jre/lib/amd64/default directory has been removed. This directory wasn't required in the past for compressed refs builds (only the compressedrefs directory was required), however now that the builds use mixed refs (both compressed refs and large heap in the same build), the default directory is required.

[bharathappali]

@pshipton yes its due to removal of default directory. In my experiment I saw the JVM coming up after commenting rm -rf default/ in jre_lib_files. Not sure which file JVM is missing among these
