How the Java Stack Trace Analyzer Works
When a Java application crashes, the resulting stack trace can be massive—often hundreds of lines long, heavily padded with internal Spring Boot, Tomcat, or Hibernate reflection calls.
This tool parses the raw text and highlights the exact lines originating from your own application code based on the base package prefix you provide. Third-party library calls are dimmed so you can instantly focus on the root cause.
