Hoss Man commented on SOLR-8689:
--------------------------------
I don't have a windows VM to use to work on this, but whoever picks it up might
want to review the corollary fixes in {{bin/solr}} over in SOLR-10184: in
particular this comment...

* fix the version parsing to look at the entire number, and compare against
entire float versions like "1.8"
* fix gc log option defaults & how log file is added
bash changes that should be mimiced in windows cmd scripting...

> Key: SOLR-8689
> URL: https://issues.apache.org/jira/browse/SOLR-8689
> Project: Solr
> Issue Type: Bug
> Components: scripts and tools
> Affects Versions: 5.5, 6.0
> Environment: Windows 7
> Reporter: Uwe Schindler
> Labels: Java9
>
> At least on Windows, Solr 5.5 does not start with the shell script using a
> Verona-Java-9 JDK:
> {noformat}
> *****************************************************
> JAVA_HOME = C:\Program Files\Java\jdk-9
> java version "9-ea"
> Java(TM) SE Runtime Environment (build
> 9-ea+105-2016-02-11-003336.javare.4433.nc)
> Java HotSpot(TM) 64-Bit Server VM (build
> 9-ea+105-2016-02-11-003336.javare.4433.nc, mixed mode)
> *****************************************************
> C:\Users\Uwe Schindler\Desktop\solr-5.5.0\bin>solr start
> ERROR: Java 1.7 or later is required to run Solr. Current Java version is:
> 9-ea
> {noformat}
> 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
