StackTrace is a tool for inspecting the state of a running JVM without starting it in debug mode and without using any additional startup settings.
StackTrace Features:
- Thread dump for Java processes running as a Windows service (like Tomcat, for example), started with javaw.exe, applets running inside any browser or JVMs embedded inside another process. StackTrace works on Windows, Linux and Mac OS X.
- Prints system properties, memory usage, and command line for any Java process.
- Starts a BeanShell interpreter inside a running Java application. StackTrace provides commands for inspecting and modifying live objects, tracking AWT/SWT events, file and network access, deadlock detection and many more.
For information about the additional commands look at the documentation.
IMPORTANT: The security manager is disabled during the time when the interpreter runs. Do not use this feature in production environment!
- Records and replays user actions. This feature can be used for automating GUI testing or for reporting and reproducing software defects.
- Redefines already loaded classes inside a running VM (Java 6 only.)
- Limited form of debugging JVMs running in production mode. Breakpoints when entering and exiting methods with an ability to inspect and modify the arguments, the return values, and the exceptions thrown from the methods (Java 6 only.)
- Fault injection testing without modification of the target program code by using the intercept() command (Java 6 only.)
