Detection problem: message/rfc822 file is detected as text/plain.
-----------------------------------------------------------------
Key: TIKA-879
URL: https://issues.apache.org/jira/browse/TIKA-879
Project: Tika
Issue Type: Bug
Components: metadata, mime
Affects Versions: 1.0, 1.1, 1.2
Environment: linux 3.2.9
oracle jdk7, openjdk7, sun jdk6
Reporter: Kostya Gribov
When using {{DefaultDetector}} mime type for {{.eml}} files is different (you
can test it on {{testRFC822}} and {{testRFC822_base64}} in
{{tika-parsers/src/test/resources/test-documents/}}).
Main reason for such behavior is that only magic detector is really works for
such files. Even if you set {{CONTENT_TYPE}} in metadata or some {{.eml}} file
name in {{RESOURCE_NAME_KEY}}.
As I found {{MediaTypeRegistry.isSpecializationOf("message/rfc822",
"text/plain")}} returns {{false}}, so detection by {{MimeTypes.detect(...)}}
works only by magic.
