Re: Re: Re: enhancement request for Ant event builder task

That's interesting because in my experience, if you have a file in the same 
package as the class loading the file, you can do this...

getClass().getResourceAsStream("myfile.txt");

that will load successfully.  However, if "myfile.txt" is in the root 
package, it will not be found.  To find it using the above, one needs to do...

getClass().getResourceAsStream("/myfile.txt");


The equivalents to the above (again, in my experience) using the 
classloader (assuming a package of org.mypackage) is, respectively...

getClass().getClassLoader().getResourceAsStream("org/mypackage/myfile.txt");

and

getClass().getClassLoader().getResourceAsStream("myfile.txt");


But, if you say it works and have tested this, then I have no problem with 
it.  And I'll just change the tabs to spaces on my end.

thanks for the patch!
