Spaces in executable name causes the program to crash

See original GitHub issue

when running mockito (and bytebuddy) in IntelliJ, the test run crashes since the java executable has spaces in the path. The problem anyhow is not spaces, but quoting paths that has spaces. Spaced paths should not be quoted. This fails when running the program.

problematic lines:

Minimal repro of quotes in file name:

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class Hello {
  
  public static void main(String []args) throws IOException {
    try {
      List<String> list = new ArrayList<String>();
      list.add("\"/Applications/IntelliJ IDEA 2019.3 EAP.app/Contents/jbr/Contents/Home/bin/java\"");
      ProcessBuilder builder = new ProcessBuilder(list);
      builder.start();
      System.out.println("finished");
    } catch (Exception e) {
      System.out.println(e);
    }
  }  
}

If I take quotes off, the program runs fine. I believe this might have been a breaking change in some Java version. I’m running java 12.0.1 and IntelliJ is running Java 11.0.4+12-b462.3 on macOS.
