Hello! Solr (i.e. Tika) throws a "zip bomb" exception with certain documents we have in our Sharepoint system. I have used the tika-app.jar directly to extract the document in question and it does _not_ throw an exception and extract the contents just fine. So it would seem Solr is doing something different than a Tika standalone installation.
After some Googling, I found out that Solr uses its custom HtmlMapper (MostlyPassthroughHtmlMapper) which passes through all elements in the HTML document to Tika. As Tika limits nested elements to 100, this causes Tika to throw an exception: Suspected zip bomb: 100 levels of XML element nesting. This is metioned in TIKA-2091 (https://issues.apache.org/jira/browse/TIKA-2091?focusedCommentId=15514131&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-15514131). The "solution" is to use Tika's default parsing/mapping mechanism but no details have been provided on how to configure this at Solr. I'm hoping some folks here have the knowledge on how to configure Solr to effectively by-pass its built in MostlyPassthroughHtmlMapper and use Tika's implementation. Thank you!
