---------------------------------
Assignee: Tim Allison
> Tika 3.3.0 Fails to Detect Media Type of Embedded Objects of LibreOffice Files
> ------------------------------------------------------------------------------
>
> Key: TIKA-4785
> URL: https://issues.apache.org/jira/browse/TIKA-4785
> Project: Tika
> Issue Type: Bug
> Components: tika-core
> Affects Versions: 3.3.0
> Environment: Java 21
> Reporter: Xiaohong Yang
> Assignee: Tim Allison

> [^Program_and_Sample_Files.zip]
> We use Tika to extract embedded objects from LibreOffice files. We also use
> Tika to get the media type of the extracted objects. We encountered an issue
> in media detection in Tika 3.3.0 in the following method. Note that there is
> no issue with Tika 3.2.3. The Java version is 21.

> public void parseEmbedded(InputStream inputStream, ContentHandler

> String fullFileName =
> metadata.get(TikaCoreProperties.{_}RESOURCE_NAME_KEY{_});
> if (fullFileName == null) {
> fullFileName = "file" + count++;
> }
> if (config == null) {
> System.{_}out{_}.println("config is null");
> return;

> MediaType contentType = config.getDetector().detect(inputStream,
> metadata);
> String tikaExtension = null;
> boolean hasExtension = fullFileName.indexOf('.') != -1;
