Rethrowing exceptions in Java without losing the stack trace

Question

In C#, I can use the throw; statement to rethrow an exception while preserving the stack trace:

try

{

   ...

}

catch (Exception e)

{

   if (e is FooException)

     throw;

}

Is there something like this in Java (that doesn't lose the original stack trace)?

Answer 1

You can try:

catch (WhateverException e) {

    throw e;

}

It will just rethrow the exception you've passed (certainly the enclosing method has to allow this via its signature etc.). The exception will preserve the initial stack trace.
