----------------------------
Hi, [~ggregory]
I have created a a merge request.
[https://github.com/apache/commons-io/pull/383]
But looks like the method works well at the current moment. The problem left
only in javadoc. I also added special tests for javadoc examples.
> FilenameUtils.normalize does not sanitize multiple slashes after prefix

> Key: IO-611
> URL: https://issues.apache.org/jira/browse/IO-611
> Project: Commons IO
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: Urvanov
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h

> FilenameUtils.#normalize states in javadoc that //foo//./bar becomes /foo/bar
> {code:java}
> System.out.println(FilenameUtils.normalize("//foo//./bar"));
> System.out.println(FilenameUtils.normalize("\\\\foo\\\\.\\bar"));
> {code}
> Result:
> {code:java}
> //foo//bar
> //foo//bar
> {code}
> So, javadoc says, that it should be /foo/bar. I think, that //foo is prefix,
> so it should be //foo/bar. But in real life it becomes the third way
> (//foo//bar).
>
> I think we should fix javadoc and the code. The correct result should be
> //foo/bar
