Previously > there was only a check if the HTTP header contained "multipart/form-data", > now there is the following regex in Dispatcher::isMultipartRequest. > > {quote}public static final String MULTIPART_FORM_DATA_REGEX = > "^multipart/form-data(; > boundary=[0-9a-zA-Z'()+_,\\-./:=?]\{1,70})?(;charset=[a-zA-Z\\-0-9]\{3,14})?";{quote} > > This is too restrictive, apache http client for example adds a white space > between the semicolon and "charset" and thus all file uploads are failing > unless this regex is overwritten in the config. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
