FAQ

Common questions about Spring Boot Root Cause Extractor.

What is a root cause exception in Spring Boot?

In Spring Boot, exceptions are often wrapped in multiple layers (e.g., BeanCreationException wrapping NoSuchBeanDefinitionException). The root cause is the innermost exception that actually triggered the failure, such as NoSuchBeanDefinitionException.

How does this tool handle nested exceptions?

It parses the log to find the deepest 'Caused by' or 'nested exception is' chain and extracts the final exception type and message, along with the most relevant stack frames.

Is my log data sent to a server?

No. All processing happens locally in your browser. Your logs never leave your device.

Can I use this for other Java frameworks?

Yes, while optimized for Spring Boot, it works with any Java stack trace that follows standard exception chaining patterns.
