Exception when running self-hosted war/jar

[alex-t0]

Hi!

I'm trying to run app as spring boot self-hosted jar, and this error occurs:

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Script engine with name 'kotlin' failed to initialize] with root cause

java.io.IOException: The filename, directory name, or volume label syntax is incorrect

Honestly, I have same error in my spring boot application: https://github.com/alex-t0/spring-boot-kotlin, and I ask question several days ago on stackoverflow: https://stackoverflow.com/questions/57727150/kotlin-script-engine-with-spring-boot-self-running-war. In my app error occurs if you uncomment this line: ScriptEngineFactoryManager().GetScriptEngine("kotlin"); in KotlinView.Render. And ScriptEngineManager(classLoader).getEngineByName("kotlin") expression returns null when launched as self-running jar. In IDEA all works fine.

May be you can help me with workaround for this error?
