-----------------------------------

             Summary: Solr 5/6 does not start with recent Java because of version parsing issue
                 Key: SOLR-8689
                 URL: https://issues.apache.org/jira/browse/SOLR-8689
             Project: Solr
          Issue Type: Bug
          Components: scripts and tools
         Environment: Windows 7
            Reporter: Uwe Schindler


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
