Comment 1 for bug 1659124

Hi, thanks for reporting this issue.

It appears this is caused by the patch for CVE-2016-6816 which tightened the validation rules for invalid characters. Unfortunately, it appears the pipe character was commonly used even though it is contrary to RFCs.

There is a bug upstream about the issue, which I've linked to this bug:

https://bz.apache.org/bugzilla/show_bug.cgi?id=60594

Ideally, your application should be modified to not use the invalid character, or if that isn't possible, downgrading the package could be a workaround until we see if upstream makes the more strict validation optional or not.
