Description of problem:

The bug occurs when form data is posted as multipart/form-data and using Servlet 3 API to get posted files. In a servlet, if we set the encoding:

request.setCharacterEncoding("UTF-8");

Then invoke:

request.getParts()

And then invoke:

String text = request.getParameter("sometextfield");

UTF-8 characters in the text have been garbled.

Version-Release number of selected component (if applicable):

7.5.22


How reproducible:

Always

Steps to Reproduce:
1. Deploy multipartdemo-0.0.1.war
2. Access /multipartdemo-0.0.1
3. Submit form with UTF-8 characters

Actual results:

Expected encoding is not properly used for multipart/form-data, resulting in bad characters.

Expected results:

Expected encoding is properly used for multipart/form-data.
