Description

The Java 9+ GC logging options in bin/solr and bin/solr.cmd specify a log rotation file size of 20000 which according to JEP 158 (https://openjdk.java.net/jeps/158) should be the "file size in kb" however when running Solr on Java 11 I'm seeing GC logs rotated every 20KB.

Changing "filesize=20000" to "filesize=20M" fixes the problem for me under Linux.
