around this issue No it doesn't seem to be possible using this class.
You have to do it manually using lower-level classes and handle yourself part numbers and ETags in a (persistant) data structure.

Jersey ApacheConnector MultiPart file upload - no multipart boundary was found

it fixes the issue Try changing the second parameter of post call with a call to MultiPartMediaTypes.createFormData(). This should create a new MediaType instance with a configured boundary, which will be picked up by the MultiPart writer.

Can I pause and resume the multipart upload using Amazon High or Low Level API?

will help you With the REST API, this is trivially simple... you "pause" by just not sending any more parts, and you "resume" by sending the next part.
The "low level API" maps closely to the REST interface, so the functionality should be the same. S3, internally, has no concept of "pausing" a multipart upload. It's just waiting -- indefinitely -- for you to upload more parts and complete the request, or to abort the request. It will store the parts you've sent (with charges for storage) until the entire operation is completed or aborted... and it will literally wait for months (I've seen it... and presumably, it will wait forever) for you to "resume."
