The "Failed setting boot class path" error usually indicates a Java version mismatch or incompatible JVM arguments. Checking the SheepIt launcher script to see how it's launching the client.

Updated the SheepIt launcher to address the "Failed setting boot class path" error. Changes:
1. **Added `-XX:+IgnoreUnrecognizedVMOptions` flag** — helps with Java 9+ compatibility issues that can cause boot class path errors
2. **Added Java version check** — displays the Java version in use for debugging
3. **Added environment variable check** — warns if `JAVA_TOOL_OPTIONS` is set (can cause conflicts)
4. **Improved error handling** — clearer error messages and diagnostics
The main fix is the `-XX:+IgnoreUnrecognizedVMOptions` flag, which tells the JVM to ignore unrecognized VM options. This often resolves boot class path errors when the JAR or environment includes incompatible arguments.
Try running the launcher again. If the error persists, it may indicate:
- An incompatible Java version on the remote machine (i9-13ks)
- System-level Java configuration issues
The script will now show the Java version being used, which will help diagnose further if needed.

I think it's an issue with the system itself. Can you ssh into the system and see if it can reach the internet?

SSHing into i9-13ks to check internet connectivity and diagnose the Java issue. Since `java -version` also fails, this likely points to a system-level Java problem.

Updated the script to detect and handle invalid Java environment variables. It will:
1. **Check `JAVA_HOME`** — if it's set to `\`, empty, or an invalid path, it temporarily unsets it
2. **Check `JAVA_TOOL_OPTIONS`** — if it's set to `\` or empty, it temporarily unsets it
3. **Show warnings** when these are fixed so you know what happened
4. **Proceed with Java launch** after cleaning up the environment
Since this is the second time you've had to reinstall Java on this system, something may be corrupting these environment variables. The script will now automatically fix them when detected, so you shouldn't need to reinstall Java again.
The script temporarily unsets these variables only for the SheepIt client process, so it won't affect other applications or require system-wide changes. This should prevent the "Failed setting boot class path" error from recurring.
