 XWIKI-3415: Office Importer fails when importing documents with TOC
 (Table Of Contents) structures
 * Fixed.
 * But there is still a problem (not a failure) with importing word
 documents with TOC structures. That's a different issue.

The best practice is never to catch an exception unless the test is
about testing for exeption use cases.
So you should instead have testAnchor*() throws Exception {...} and
don't put put the try/catch.
see 
http://junit.sourceforge.net/doc/faq/faq.htm#tests_8 for example.
