Is Advanced Java Launch safe?

Low risk

Advanced Java Launch relays page-supplied download specs to a native application to download and execute Java resources.

The extension's content script, active on any domain matching *://*/cp/*.do, listens for postMessage events from the page and forwards caller-supplied download specifications to the service worker. The service worker downloads the listed resources via chrome.downloads and then passes the full download spec to the AdvJavaLaunch native application for execution, without validating resource URLs or hostnames.
