Note that the script can access Java methods/properties of objects explicitly exposed via javax.script.ScriptContext/Bindings (if any). If those are also empty, then global scope gets nothing from Java.

If you want, you can manually delete these properties or assign undefined to these by writing a simple init script that is loaded upfront - before running the actual script.
