This PR is to Ignore JVMJ9VM090I messages in java -version output.

it should fix the related issue reported in to eclipse-openj9/openj9#12470. Meaning, next time we encounter network issues which cause java -version to output JVMJ9VM090I as below, STF would ignore it and continue.

GEN stderr Exception in thread "main" net.adoptopenjdk.stf.StfException: 'Java -version' output does not start with 'java version'. Actual output was: JVMJ9VM090I Slow response to network query (160 secs), check your IP DNS configuration
GEN stderr openjdk version "11.0.11-internal" 2021-04-20
GEN stderr OpenJDK Runtime Environment (build 11.0.11-internal+0-adhoc.jenkins.BuildJDK11ppc64aixNightly)
GEN stderr Eclipse OpenJ9 VM (build master-22fc5113773, JRE 11 AIX ppc64-64-Bit Compressed References 20210418_687 (JIT enabled, AOT enabled)
GEN stderr OpenJ9   - 22fc5113773
GEN stderr OMR      - 0f967b721d2
GEN stderr JCL      - ba1caf576ee based on jdk-11.0.11+8)

Tested : internal/Grinder/14822

Note: the original issue which causes java -version to output JVMJ9VM090I was not reproducible.

It should be more robust to skip anything that starts with "JVMJ9VM" rather than these specific messages. Not sure if there are other possibilities besides these two, and additional ones could be added in the future.

I see! Agreed. Updated PR.

Does it make sense to use String.matches() with regex (openjdk|java) version? We just need to validate that java -version output contains (openjdk|java) version. Does it matter if it contains any other messages?

We just need to validate that java -version output contains (openjdk|java) version

The way this piece of STF code was implemented is suggestive of the fact that the people involved in coding it had decided to validate if java -version output starts with 'java version'. I have no knowledge of why they decided to do that.

If we want to change this check's criteria, we can change it to whatever we want. We just need to come to an agreement. That's all.

@llxia : As discussed at the AQAvit call, could we deliver this PR so that it unblocks build from any reoccurrence of the issue reported in eclipse-openj9/openj9#12470?

As the next step, I'll create a second issue to remove the version check altogether and update the logic of figuring out various Java versions in JavaVersion.java to depend on Java system properties instead of parsing java -version output.

We are still technically in a code freeze for release week.

That was a slip from my side!
