[eclipse-dev] recent change causes pde-build to fail on phantom dependen

[Stephan Herrmann <stephan.herrmann@xxxxxxxxx>]

Hi,

I'm searching for some change in the Eclipse SDK
which occurred between
 - I20150422-1000 (good)
and
 - I20150426-2000 (broken)
that could possibly influence pde-build into reporting
the following cycle:

A cycle was detected when generating the classpath org.eclipse.objectteams.otequinox.branding_2.3.0.201406101339, 
org.eclipse.ui.workbench_3.107.0.v20150427-1733, org.eclipse.e4.ui.workbench.renderers.swt_0.13.0.v20150422-0725, 
org.eclipse.e4.ui.workbench.swt_0.13.0.v20150422-0725, org.eclipse.e4.ui.css.swt_0.12.0.v20150422-0725, 
org.eclipse.e4.ui.css.swt.theme_0.10.0.v20150422-0725, org.eclipse.e4.ui.css.swt_0.12.0.v20150422-0725.

I'm not sure if we are searching for a configuration change
near the o.e.e4.ui.css.swt.* bundles, or for a change near
equinox/p2 that breaks classpath computation.

The bundle that triggers this bug simply has this dependency:

Require-Bundle: org.eclipse.ui.workbench;bundle-version="[3.7.0,4.0.0)"

I originally reported this against pde build at
   https://bugs.eclipse.org/465714
Since pde-build doesn't have any changes in that window
they can't be blamed, however.

Given the narrow window of just 4 days, can anyone build
a theory what change might cause this bug?

thanks,
Stephan
