+SYSTEM PROPERTY: -Dnashorn.anonymous.classes.threshold=<value>
+
+Nashorn can use anonymous classes for loading compiled scripts, depending
+on the --anonymous-classes=[auto|true|false] option. Anonymous classes load
+faster, but the loaded classes get less optimization applied to them and
+therefore usually run slower. In the default "auto" setting, scripts are
+loaded as anonymous classes if the script size does not exceed 512 bytes.
+The above system property allows to set this threshold to a user defined
+value.
