[wtp-dev] Restricted Access warnings?

[David M Williams <david_williams@xxxxxxxxxx>]

Lawrence, you asked about "restricted
access warnings" ... are you seeing 
Access restriction: ... 
or 
Discouraged Access: .... ?


Access restriction: 

This is a worse warning, and a sign
of run-time trouble.  I know M5 had some bugs that caused us to have
some spurious ones (related to 3rd party jars), but believe these should
be fixed in M6, but have not checked. So, if you still see these, point
me to a few, or open a bugzilla, and we'll investigate. (I do not see any
in my workspace, so .. if you do, might be a set up problem? Or ... some
other bug?). 

Discouraged Access 

Yes, there are 15,000 of these, and
they are normal (and should be turned off or filtered out, , if  causing
clutter for you). 



To summarize policy: speaking as PMC
member and Architecture Group Lead, 
our policy is the same as the Eclipse
Project policy: 
expose everything by listing all packages
in the manifest.mf files, but 
use x-internal to mark any packages
which are not official, complete,  and binary compatible API 
(which includes all packages with 'internal'
in the name). 

We realize this causes lots of warnings,
(if you don't change the default settings or filters). 
but, our policy is its best to be conservative
(yet accurate) on what we imply is API, 
rather than risk adopters being surprised
later. Adopters can turn off the warnings, once they "accept the risk"

of using non-API, if they do in fact
extend WTP in those ways. 

Also, our architectural goal is to have
clean component-subsystems (eventually) so the "x-freinds" relationship

can not span the component-subsystem
boundary. (so for example, dtd or xsd can use xml internals, 
but something in HTML or JSP should
not .. and while it currently has to, again, its best to have accurate
manifests now). 

Hope this helps,

I've also noticed a lot of restricted access warnings in my workspace.
Is our policy at this time to expose all functionality to extenders or
to restrict some packages so these warnings show up?

I sure hope you are using M6! :)  Especially since we are building
with it now!   

If so, and if you have all/most of our WTP plugins loaded, have you noticed
there's a ton of new errors?  similar to 

      "The type org.eclipse.core.resources.IResource
cannot be resolved. It is indirectly referenced from required .class files"

Which results in nothing much building (in the workspace, builds fine in
batch mode, and runs fine). 

I'm not sure what changed to cause this change, or what "right"
solution is. 
But, the easiest solution is to add things like core.resoruces to the manifest.mf
file. 
core.resources is probably easy and obvious ... everyone needs that, right?
but emf.ecore was another that will have to be added to some... that's
less desirable to "require", I'd guess.

Anyone else want to propose a solution?
