> In the Java source of HarFileSystem.java:
> {code:title=HarFileSystem.java|borderStyle=solid}
> ...................
> ...................
> private Path archivePath(Path p) {
> Path retPath = null;
> Path tmp = p;
>
> // I think p.depth() need not be loop many times, depth() is a complex calculation
> for (int i=0; i< p.depth(); i++) {
> if (tmp.toString().endsWith(".har")) {
> retPath = tmp;
> break;
> }
> tmp = tmp.getParent();
> }
> return retPath;
> }
> ...................
> ...................
> {code}

> I think the fellow is more suitable:
> {code:title=HarFileSystem.java|borderStyle=solid}
> ...................
> ...................
> private Path archivePath(Path p) {
> Path retPath = null;
> Path tmp = p;
>
> // just loop once
> for (int i=0,depth=p.depth(); i< depth; i++) {
> if (tmp.toString().endsWith(".har")) {
> retPath = tmp;
> break;
> }
> tmp = tmp.getParent();
> }
> return retPath;
