Hi,
I'm not sure that I understand your proposal. Even if we provide a Loader class
in 2.0 it won't be compatible on a binary level as there are many other changes.
The idea to use PDFBox 3.0.0 in environments where other dependencies are
compiled against 2.0.x won't work. Or do I miss something?

Hi,
I’ve one point which is not per se related to the 3.0 beta release, but which
should be considered:
The 3.0 release changed some APIs in a source and binary incompatible way. E.g
instead of using the PDDocument.load() method you now use the Loader class etc.
It would be extremely helpful if PDFBox 2.0 could provide a kind of „Shim“
which provides the 3.0 API. E.g. implement a Loader class in PDFBox 2.0 - which
internally just uses PDDocument.load(). At the same time you could depreciate
the load() method in the PDDocument and document that the Loader should be used.
This would allow to „migrate“ projects using PDFBox 2.0 to the 3.0 API while
staying on PDFBox 2.0. As PDFBox 3.0 has the same namespace as PDFBox 2.0 I
think this is needed to make the migration path as smooth as possible.
Rational: More and more projects use PDFBox directly or indirectly (e.g. by
using my PDFBox-Graphics2D wrapper - Apache POI for example). When you have a
complex application you might have many dependencies which will pull in PDFBox
2.0. If they can work with PDFBox 3.0 because they migrated the API usage to
the new API using the shim in PDFBox 2.0 you can upgrade to PDFBox 3.0 in your
project. I.e. the lib targets PDFBox 2.0 but would work with 3.0.
Otherwise you can only consider a upgrade to PDFBox 3.0 in your application
after the last dependency has migrated to PDFBox 3.0. Which might take a long
time…
I.e. at the moment as PDFBox 3.0 has the same namespace as PDFBox 2.0 just
upgrading to PDFBox 3.0 will break many things in dependencies. So you have to
stay on 2.0 as long as not all dependencies have migrated...
It would be very nice if we could avoid a version mess here.
Greetings

Hi,
I'm planning to cut our first beta release of 3.0.0. Be aware that the api is
supposed to be stable after the release.
Are there any objections? Are there any tickets which should be solved before?
