If you try to start Solr on Windows with Java 10, it fails with the following message:
Java 8 and Java 9 works. I did not try Linux, but the version parsing on Windows is so braindead (i tried to fix it for Java 9 already). Windows CMD shell does not know any numerical comparisons, so it fails as "10" is alphabetically smaller "9".
I hope this is better on Linux.
Why do we have the version check at all? Wouldn't it be better to simply wait for a useful message by the Java VM on startup because of wrong class file format? This is too simply to break, especially as the output of "java -version" is not standardized (and changes with Java 10 to also have a date code,...). It also may contain "openjdk" instead of "java".
So please please, let's get rid of the version check!
