Understood. My goal here and with the preceding ones in `ZipFile` and `URLClassPath` was to remove ArrayDeque from startup of a simple `java -cp file.jar` program. No plans to go hunting for more after this.   

Specifically for this change: Do you have any sense if `new ArrayList()` would be beneficial here, given that ArrayLIst provides lazy initialization of the elements array while ArrayDeque does not and allocates 17 elements per default constructor?

In other words, is it common for this stack to be empty?
