Fetching Full stacktrace Exceptions

I am trying to update the Apache lang dossier from 2.4 to 3.1 in my project. In my implementation, there is a link to ExceptionUtil.getFullExceptionTrace (e), which no longer exists in 3.1. Reason for deletion is indicated as

"Removing isThrowableNested, isNestedThrowable and getFullStackTrace since they were all no-op types as soon as you got into JDK 1.4. LANG-491"

. A few questions about this change:

  • I am confused if this means that we need to learn another way to get the full stack trace, otherwise we can replace ExceptionUtils.getStackTrace (e) instead.

  • Any idea on what has changed since jdk 1.4 to make the method redundant?

  • Can't we just do e.toString (), where e is my instance of Exception?

thanks

Java 1.4 introduced the getCause () method for the Throwable class, which is the parent of all exception classes. If you need to get the stack trace as a string, you can use ExceptionUtils.getStackTrace (e) or something like this:

Exception e = ... StringWriter sw = new StringWriter(); e.printStackTrace(new PrintWriter(sw)); String stack Trace = sw.toString();

See additional discussion about removing methods from ExceptionUtil for JIRA LANG-491 issue .
