I wrote a Jersey class that was supposed to accept a multipart/form-data encoded POST from a html form. It returned a 400 error. Digging into the actual problem, I found that a MIMEParsingException is being thrown by mimepull (a Jersey dependency). The body of the post is getting corrupted somehow. I've confirmed that the Jersey class is working correctly by deploying it in a Jetty container and testing it there.

Until this gets fixed, I can't create a web service that accepts files
