Hi,

Thanks for the bug report. Please report on the following:

• Is your Java SDK an official Oracle one or OpenJDK?
• What Java SDK version are you using?

This errors looks to me like an Java SDK one and if that's the case, I'll be unable to help.
I advise you install latest JDK from official Oracle store and try again.

Regards,
Mariusz.

❯ java -version
java version "12.0.1" 2019-04-16
Java(TM) SE Runtime Environment (build 12.0.1+12)
Java HotSpot(TM) 64-Bit Server VM (build 12.0.1+12, mixed mode, sharing)

Could it be that the Oracle JDK version is lower? I then tested it after updating Oracle JDK.

Thank you for your reply.
