------------------------------------
> Encoded characters in URI are decoded multiple times during preprocess
> ----------------------------------------------------------------------
>
> Key: CXF-6606
> URL: https://issues.apache.org/jira/browse/CXF-6606
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.1.2
> Reporter: Tyler Brazier
> Assignee: Sergey Beryozkin
> Fix For: 3.1.3, 2.7.18, 3.0.7
>
>
> When given a url like {{/api/%255E/users.json}},
> {{RequestPreprocessor#preprocess}} first does {{handleExtensionMappings}},
> which creates a {{PathSegmentImpl}} with a single arg constructor, decoding
> the path. The path on {{Message}} is set to the decoded path with a call to
> {{updatePath}} if the {{.json}} extension was found within the extension
> mappings. Back in {{RequestPreprocessor#preprocess}}, the path returned will
> be decoded again within the call to {{UriInfoImpl#getPath}}.
> This causes the {{%255E}} in the path to be decoded the first time as
> {{%5E}}, then the second time as {{^}}.
> I believe this could be fixed by constructing {{PathSegment}} within
> {{handleLanguageMappings}} and {{handleExtensionMappings}} with a second
> {{false}} argument.
