Uwe Schindler commented on SOLR-8689:
-------------------------------------
I rewrote the WIndows startup script, but I stumbled on an issue with the Java
9 command line parser. I asked on the Hotspot Mailing List:
http://mail.openjdk.java.net/pipermail/hotspot-dev/2017-August/027962.html

I am currently adapting Apache Solr's startup scripts for Java 9. Linux was
already done at the beginning of this year and works perfectly, but Windows
brings some problems. I already fixed version number parsing, but I stumbled on
the following: In the Windows ".cmd" shell script it uses the following to
enable Garbage collection logging to a separate file, if Java 9 is detected:
set
GC_LOG_OPTS="-Xlog:gc*:file=!SOLR_LOGS_DIR!\solr_gc.log:time,uptime:filecount=9,filesize=20000"
The problem is now that "!SOLR_LOGS_DIR!" is already expanded to an absolute
Windows Path by the shell and therefore starts with "C:\". The problem is now
the colon, which breaks the log parsing. When Java 9 starts it exits with the
following parsing error:
Invalid -Xlog option '-Xlog:gc*:file=C:\Users\Uwe
Schindler\Projects\lucene\trunk-lusolr1\solr\server\logs\solr_gc.log:time,uptime:filecount=9,filesize=20000'
If I replace with a simple file name, without path/drive letter it works. How
to escape the colon in the drive letter correctly, to me this looks like a
bummer?

> Project: Solr
> Issue Type: Bug
> Components: scripts and tools
> Affects Versions: 5.5, 6.0
> Environment: Windows 7
> Reporter: Uwe Schindler
> Priority: Blocker

> At least on Windows, Solr 5.5 does not start with the shell script using a
> Verona-Java-9 JDK:

> I don't know if this is better with Linux, but I assume the version parsing
> is broken (e.g., String#startsWith, interpret as floating point number,...)
> We should fix this before Java 9 gets released! The version numbering scheme
> changed completely: http://openjdk.java.net/jeps/223
