System.console() Returns Null in Eclipse Debug Mode
When using the readLine method of BufferedReader to read input or a new password from a user, masking the password with the java.io.Console class is preferred. However, encountering a null return from System.console() while debugging in Eclipse can be frustrating.
Unfortunately, this issue is attributed to a bug (#122429) in Eclipse itself. The workaround involves disabling console logging during debugging:
- Navigate to the Eclipse Preferences window (Window > Preferences on Windows/macOS, Eclipse > Preferences on Linux).
- Expand the "Java" node and select the "Console" subcategory.
- Clear the "Show console only for active contents" checkbox.
This modification allows System.console() to function correctly even when debugging in Eclipse.
