INSERT DATA { } requests with more than roughly 5K triples can/will throw StackOverflowExceptions due to an issue with the underlying Jena libraries discussed here:
[https://mail-archives.apache.org/mod_mbox/jena-users/201601.mbox/%3C568BA9FB.5090709@apache.org%3E]
The workaround mentioned (to use the "ARQ" parser instead of the "SPARQL" parser) is what I have been using for some time, and does indeed avoid the problem. It is not immediately clear whether newer versions of Jena still exhibit this issue.
In edu.cornell.mannlib.vitro.webapp.controller.api.SparqlUpdateApiController, I changed the line around line 94 to:
return UpdateFactory.create(update, Syntax.syntaxARQ);
