[FIXED] Error:java: invalid flag: -release

Issue

I use Java :

Java(TM) SE Runtime Environment (build 9-ea+143) Java HotSpot(TM) 64-
Bit Server VM (build 9-ea+143, mixed mode)

and IntelliJ IDEA:

IntelliJ IDEA 2016.2.5 Build #IU-162.2228.15, built on October 14,
2016

Get error when compiling:

Error:java: invalid flag: -release

Executing javac -help :

--release <release>
        Compile for a specific VM version. Supported targets: 6, 7, 8, 9

So javac should use two hyphens with release, but Intellij Idea use with one.

Can I override javac options that IDEA use or fix it in some way?

UPD: Even Build, Execution, Deployment > Compiler > Java Compiler Additional Command Line Parameter doesn't help in this case

Solution

Java 9 support is cutting edge and should be tried with the most current version. At the moment, this is the public preview of 2016.3, available here.
