CommandLineWrapper is ill-suited error using modern IntelliJ and Java

[MosheElisha]

Hi,

When using the plugin with a more recent IntelliJ (mine is 2020.1) and Java >= 9, I get the following error:

`CommandLineWrapper` is ill-suited for launching apps on Java 9+.
If the run configuration uses "classpath file", please change it to "@argfile".
Otherwise, please contact support.

This is due to a change done in IntelliJ - JetBrains/intellij-community@3de0403
