According to the [support matrix](https://www.elastic.co/support/matrix#matrix_jvm), Elasticsearch 6.2 supports Java9, but Logstash does not. ---

I'm also attempting to import MS-SQL data into Elasticsearch on a Windows platform and got the same error as jmota. Can you tell us any way to work around this problem? I've looked for a JDK for Windows that Logstash is compatible with but haven't been successful (but I may have just missed something). I'll be grateful for any guidance you can give. ---

> I've looked for a JDK for Windows that Logstash is compatible with but haven't been successful (but I may have just missed something). Googling "download java 8 windows" leads me to [http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) so I'm not sure what problems you've been having. ---

So Java 8 is the same as "Oracle JVM 1.8u60+"? That wasn't clear to me and explains why I didn't find anything when I searched. Thanks. ---
