Shawn Heisey commented on SOLR-7748:
------------------------------------
bq. wether the script should explicitly fail/warn "IBM J9 is known to have
problems running Solr" on startup is a question that should be
discussed/answered in it's own issue – it certainly makes sense to me to go
ahead and fix the script to not fail in a weird and confusing way just by the
coincidence of trying to use J9.
bq. The issues that are known to cause corruption are suspected to have been
fixed, but since they were not reproducible with the latest j9 builds, we can't
say it for sure
bq. With this patch, we have a way to also detect particular build versions and
block them if we know they are bad.
Since we think IBM has fixed the problems, allowing J9 makes sense, and we can
handle about further version detection and resulting actions on another issue.

> bin/solr doesn't work on IBM J9 because it sets -Xloggc flag, while J9
> supports -Xverbosegclog. This prevents using bin/solr to start it on J9.
