------------------------------------------------------------
Tika's behavior, even in 1.16, was to sniff the bytes and trust those over what
comes in via the metadata's {{Content-Type}}. Before, you weren't sending any
bytes, so it relied on what you told it. Now, you're sending bytes to avoid
the {{ZeroByteException}}, and it is sniffing those bytes, detecting text and
ignoring the mime you are sending in.
To trigger the BlockingParser:
1. Change the line you mentioned above to:
{noformat}
resource.setProperty("jcr:data", "<?xml version=\"1.0\"
encoding=\"UTF-8\" ?>
<blocked>FOOBAR</blocked>", PropertyType.BINARY);
{noformat}
2. Add a file called {{custom-mimetypes.xml}} in
{{test/resources/org/apache/tika/mime}} that looks like this:
{noformat}
<?xml version="1.0" encoding="UTF-8"?>
<!-- ASL 2.0 -->
<mime-info>
<!-- add this for detection to trigger the BlockingParser -->
<mime-type type="application/x-blocked">
<root-XML localName="blocked"/>
<sub-class-of type="application/xml"/>
</mime-type>
</mime-info>
{noformat}
As a side note: if you want to override the detector and have it believe
whatever you tell it the file is, you can do this with
{{TikaCoreProperties.CONTENT_TYPE_OVERRIDE}} as of 1.17.
