I've made some improvements to the APIs involved with serializing and parsing HTTP parts (e.g. headers, form data, query parameters, path variables). This was based on pain-points experienced by the Apache Streams team using the client and proxy APIs. My hope is that this simplifies their code.
I've added a new package in the juneau-marshall project:
I removed the part handling code in the UON and URL-encoding marshallers and put them in these classes.
The SimpleUonPartSerializer implementation treats everything as plain-text except for beans and maps (which continue to be serialized as UON objects). This is now the DEFAULT part marshaller in both the client and server APIs. So if you were creating your own part serializers (or using StringReaders) to get around how strings were being serialized by UrlEncodingSerializer, this change lets you get rid of them.
This change sacrifices "purity" for "practicality". It should make adoption considerably easier.
Note that this replaces the existing PartSerializer/PartParser/PartType classes, so there will be code adoption. But it should be straightforward.
