libmimepull-java 1.9.7-2 (s390x binary) in ubuntu lunar

 Mimepull provides a streaming API to access attachments parts in a MIME
 message. It's designed to parse large MIME messages that couldn't be loaded
 into memory. MIME message parsing is done using pull-parsing, much similar
 to StAX in XML world. The MIME parts are constructed lazily, and parsing
 is triggered by applications while reading the attachment parts. The API
 provides various configuration options to control parsing and storing of
 MIME parts.
