I just verified 2 things on both Linux and OS X:
 # "filesize=20M" syntax works on Java 9, Java 10 and Java 11
 # "filesize=20000" is treated at 20,000 bytes on Java 9, Java 10 and Java 11

I have NOT tested on Windows.

[~thetaphi] The PR includes changes for both solr/bin/solr and solr/bin/solr.cmd so as far
as I can tell it does keep the Windows version in sync.  Am I missing something?

> 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.
