Rethrowing exceptions in Java without losing the stack trace

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)?


catch (WhateverException e) {
    throw e;
}

will simply rethrow the exception you've caught (obviously the surrounding method has to permit this via its signature etc.). The exception will maintain the original stack trace.


I would prefer:

try
{
    ...
}
catch (FooException fe){
   throw fe;
}
catch (Exception e)
{
    // Note: don't catch all exceptions like this unless you know what you
    // are doing.
    ...
}

You can also wrap the exception in another one AND keep the original stack trace by passing in the Exception as a Throwable as the cause parameter:

try
{
   ...
}
catch (Exception e)
{
     throw new YourOwnException(e);
}

In Java is almost the same:

try
{
   ...
}
catch (Exception e)
{
   if (e instanceof FooException)
     throw e;
}

In Java, you just throw the exception you caught, so throw e rather than just throw. Java maintains the stack trace.
