This is a sample project whose purpose is to demonstrate an issue when using tomahwk's inputFileUpload component with the latest version of Jetty.
The issue occur on all versions of Jetty >= 9.2.7. An exception is raised (java.io.IOException: Missing content for multipart request) when a file is uploaded. In previous versions of Jetty the same error was logged as a warning only. Looking at Jetty's 9.2.7 changelog I believe it is related to the changes made to resolve this issue 455655 ensure multipart form-data parsing exception thrown to servlet
Here is the complete stacktrace for reference:
