I need a Java preprocessor.

I like to have line numbers with my exceptions. Currently, I put them in statically.

try{
...
}catch(Exception e)
{  System.out.println("Exception at line LINENUMBER: "+e);  }

Or I will put it into my custom logger class that has the same format.
The best way that I have found to do this so far is:

String linenumber = new Exception().getStackTrace()[0].getLineNumber();
System.out.println("The line number is " + linenumber);

The problem with StackTrace is that it brings things to a halt.
