Problem with RegexFileFilter

[Oscar Besga Arcauz <os...@panel.es.INVALID>]

Hi all

In our project we want to upgrade the commons-io library to the newest version.
However, in our tests, we have found errors related to RegexFileFilter.
Oddly, the error raises in linux but not in windows, so we wonder what are we doing wrong

We want the filter to search for files to be later deleted, and we use these filters in the test.
We use two regexp filters inside a OrFileFilter

This is the log
OrFileFilter(RegexFileFilter [pattern=^.*12345ToBeDeleted.*],RegexFileFilter [pattern=^.*43210ToBeDeleted.*]

I see no differences between Linux and Windows executions, and I don't have a clue on what could be happening.


Thanks in advance

Hello,

What is the error? Do you have a stack trace?
If you can provide a unit test or a small reproducer, we can have something
no test.

Ty,
Gary
