Clean workspace, nightly target from Oct 28, 2015. Running a snippet that includes fileupload (RWT launcher) leads to the following exception. I don't have any org.eclipse.rap.* bundles in my workspace, so I'm sure that all bits are coming from this target.

Comment 2 Markus Knauer

That is an unfortunate series of events. Good that we found so quickly!

The problem is fixed in the updated nightly build at

  http://download.eclipse.org/rt/rap/nightly/runtime/

but the org.eclipse.rap.filedialog_3.1.0.20150901-0753.jar bundle that caused the exception needs to be removed manually if it had been downloaded in an earlier build/target resultion.


Background of this bug:

- The org.eclipse.rap.rwt and the org.eclipse.rap.filedialog bundles both provide classes in the org.eclipse.swt.widgets package namespace.

- Due to several other reasons, the RAP 3.1.0 M2 build could not be signed. We had to contribute it to the Neon M2 Simultaneous Release build with unsigned artifacts.

- Since yesterday our *nightly* build job is signing its output again after a long period of producing only unsigned bundles.

- Since yesterday we enabled the comparison against a baseline-repo (which included the M2 repository with the unsigned content)

Because of these reasons, the otherwise unchanged filedialog bundle had been replaced during build time with the unsigned version which made it impossible to use it together with the signed org.eclipse.rap.rwt bundle.

The baseline-repo is now disabled in the build. It should be enabled again, after we deliver our signed M3. At the same time we should remove the M2 build from the composite repository to prevent other problems in that area.

Probably we forgot to close the bug. Closing now.
