Cross project issues
New Certificate warning
You may be aware that Eclipse bundles have been signed with a new
certificate for the last two weeks. .
The new certificate seems fine with OSGI class loaders, but causes a
problem with a naive class loader such as the simple Java class loader
used when running simple JUnit tests. This class loader reports
certificate conflicts on partitioned bundles such as org.eclipse.ui 
and org.eclipse.core.runtime .
If your project has any package that is partitioned across bundles, I
strongly recommend that you ensure a consistent certificate by touching
all containing bundles before M6 to avoid problems for headless users.
