[jira] [Comment Edited] (SOLR-8689) bin/solr.cmd does not start
with recent Verona builds of Java 9 because of version parsing issue
[ https://issues.apache.org/jira/browse/SOLR-8689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16134787#comment-16134787 ]

--------------------------------------------------------------
I reordered the checks. Java 9 is detected before IBM J9. Because IBM J9 for Java 9 will handle the command line options like Oracle. This goes in-line with [~hossman]'s UNIX shell script.
I just noticed: JAVA_BUILD is not used anywhere, may I remove it? Because this wouldn't ever work with Java 9, as build numbers are handled by other means (no "_"). The UNIX shell script does not have any build version parsing, so I think it's a relict from former times.

> 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
