Time to start: As soon as possible

Project description:
"My existing application is entirely in Java, so I need a pure-Java module that will collect the current play-count for every track listed in a plain-text file (one Spotify URL or URI per line).

Key requirements
• Use Chrome DevTools Protocol (chrome api) directly through WebSocket—no Selenium, no Playwright, no exceptions.
• Spin up multiple worker threads to process many tracks in parallel; the thread count should be configurable so I can fine-tune speed vs. rate-limit risk.
• Write the results to a simple plain-text file: each output line “<track-id>|<play-count>”.
• Handle common failure cases gracefully (timeout, 429, missing track) and retry a limited number of times before logging the error line.

Deliverables
Well-structured Java source (SWING)

I already have a small code snippet that opens a CDP session; you’re free to build on it or start fresh. Speed is important, so please respond only if you’re comfortable coding multithreaded Java and the Chrome DevTools Protocol.


coder will enjoy alot of work related to chrome api" (client-provided description)
