Solutions

1. Delete the JRE folder under the cache directory so Selenium Manager re-downloads the runtime
2. Verify the Adoptium download completed (check network/proxy settings and retry)
3. Install a JDK/JRE manually and ensure it is on PATH so Selenium Manager can use the system Java

When it happens

Trigger: Thrown at rust/src/jre.rs:159 when the library encounters an invalid state.

Common situations: Occurs when the downloaded Java runtime archive does not contain the expected directory structure, usually from a corrupted download or upstream packaging change. Clear the Selenium Manager cache and retry; if persistent, report the upstream layout change.
