Description:
Running Web Console v5.0.8 with Java 21 throws ClassCastException when trying
to open the "System information" page (via the "/vmstat" web console URL).
Here is the snippet reporting the exception error:
{code:java}
java.lang.ClassCastException: class java.lang.String cannot be cast to class
java.lang.Integer (java.lang.String and java.lang.Integer are in module
java.base of loader 'bootstrap')
