Troubleshooting "java.net.BindException: Address Already in Use: JVM_Bind" Error

The "java.net.BindException: Address already in use: JVM_Bind" error occurs when an application attempts to bind to a port that is already in use. This error recently surfaced in Eclipse, leaving users perplexed about its sudden appearance.

To determine the cause of the error, follow these steps:

1. Determine the Port Number

Use the command "lsof -i:" to identify the process using the specified port. For example, "lsof -i:8080" will list the process listening on port 8080.

2. Kill the Conflicting Process

Once the conflicting process is identified, terminate it using the command "kill ", where "" is the process identifier.

3. Restart the Application

Restart the application after killing the conflicting process. The error should no longer appear.

Additional Tips

• Check if other applications are running on the same port.
• If restarting the application does not resolve the issue, check the firewall settings and ensure that the port is not blocked.
• Consider using alternative port numbers for your application to avoid conflicts in the future.
