[jira] [Commented] (LUCENE-6538) Improve per-segment diagnostics for IBM J9 JVM

    [ https://issues.apache.org/jira/browse/LUCENE-6538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14579486#comment-14579486 ] 

Robert Muir commented on LUCENE-6538:
-------------------------------------

do we really need addSysPropIfNotNull(diagnostics, "java.vm.version") ?

Why not just this:
{code}
diagnostics.add(.., System.getProperty("java.vm.version", "undefined"));
{code}

> Spinoff from http://lucene.markmail.org/thread/dq4wioomu4o346ej where I noticed that the per-segment diagnostics (seen from CheckIndex) only report 1.7.0 as the JVM version, without any update level.
> Talking to [~rcmuir] it looks like we just need to add java.vm.version and java.runtime.version sysprops into the diagnostics.
