Description

RFC 822 defines a field as:
field = field-name ":" [ field-body ] CRLF
field-name = 1*<any CHAR, excluding CTLs, SPACE, and ":">

This implies that a field name must consist of at least one character and may not contain spaces or tabs; not even trailing ones.

Currently o.a.j.mime4j.parser.AbstractEntity#parseField accepts empty field names while o.a.j.mime4j.field.Field#parse accepts trailing spaces and tabs.
