Uwe Schindler commented on SOLR-10184:
--------------------------------------
See https://bugs.openjdk.java.net/browse/JDK-8170636 about this. But this is
work in progress, as far as I see. Maybe it changes until final release. But we
should update all the start scripts to use the new {{-Xlog}} options instead of
the old ones, if Java 9 was detected.
> bin/solr fails to run on java9 due to unrecognized GC options
