There is a known issue in the MP4 parser that temporary files in tomcat/tmp folder are not deleted properly.

• https://issues.apache.org/jira/browse/TIKA-3203

There is a fix, so a version bump should solve the case.

Steps to reproduce:

1. Start a Liferay Tomcat bundle
2. Check the size of Tomcat's temp folder
3. Upload the attached mp4 file
4. Check the size of Tomcat's temp folder again

ExpectedResult:
A slight to none increase in the size of tomcat/tmp folder
Actual Result:
There is a huge increase in size because multiple accesses of the mp4 file generates temp files that are not cleaned up properly.

Reindexing DLFileEntries generates even more temp files, raising the size further.
