ObjectStreamClass.newInstance is package private and never meant to be 
used from outside of the java.io package. So the warning is correct and 
can only be suppressed by using `--add-open` to explicitly open the 
package. The warning or the use of `--add-opens` serves as remainder 
that this code is hacking into the JDK and that the hack break at some 
point.
