Bug ID: 57528
Summary: Random NPE when sending multipart content
Product: Tomcat 8
Version: 8.0.18
Hardware: PC
Status: NEW
Severity: major
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: gdog...@gmail.com
>From time to time I get a NPE when calling a rest api with
content-type=multipart/form-data
The request does not get to spring framework filters, it fails inside tomcat.
I am not using web sockets in my app
The same bug is reproducible both on linux and windows, with the zip version
and tomcat 8.0.18 (I think also with tomcat 7 and older versions of 8)
