ktlint exception when using java 9

[impatient]

Using ktlint from brew, version 0.15.0. Works fine on Java 8, switched to Java 9 using jenv and get the following error.

Exception in thread "Thread-0" java.util.concurrent.ExecutionException: java.lang.NoClassDefFoundError: Could not initialize class com.github.shyiko.ktlint.core.KtLint
	at java.base/java.util.concurrent.FutureTask.report(FutureTask.java:122)

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.github.shyiko.ktlint.core.KtLint

Command is simply: ktlint

#153 merged in but there are still couple of things that need to be fixed before this ticket can be closed:

$ ktlint --version
null

and

$ ktlint
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.jetbrains.kotlin.com.intellij.util.text.StringFactory (file:/tmp/ktlint/ktlint/target/ktlint) to constructor java.lang.String(char[],boolean)

+ verify together with maven/gradle.

[ifrins]

The exception and the version showing have been fixed. What’s remaining is the illegal reflective access. This is a Kotlin compiler that has already been resolved upstream KT-19051 and will land when Kotlin 1.2.30 is released.

@shyiko do you have any plans for a release that is compatible with java 9?

[shyiko]

@ifrins as soon as Kotlin 1.2.30 is out

[shyiko]

UPDATE:

0.16.0 released with @ifrins fixes included (thank you once again, Francesc!).

kotlin-compiler@1.2.30 hasn't been released yet so "An illegal reflective access operation has occurred" warning is still printed (to stderr) but other than that it appears to be working.

[shyiko]

ktlint@0.18.0 with kotlin-compiler@1.2.30 is out. Java 9 support is now official. Thanks everyone 🙇‍♂️

what about jdk 11?
