RE: [gmf-dev] Failing JUnits in the GMF build...

[Steven Shaw <steveshaw@xxxxxxxxxx>]

I agree as a framework we should be
more resilient to these types of issues.  Can you log a bugzilla to
runtime-common describing / capturing your ideas below?

Thanks,

Steve.

Hi!
    BTW,
it seems like any "incorrectly written" provider (throwing exception
from "provides()" operation) plugged into the IBM runtime will
block all the rest of functionality. It sounds like a stability problem
of a framework.
    I know that there
are two ways to handle this situation: one is just to throw an exception
(as it is now) - as a result one incorrect provider will block all operations
of this type. Another is to catch this exception in a framework, log it
and continue working with another providers. In other words, second approach
means: try to continue working even if one provider was broken.

    So,
my question is: will we continue working with first type of providers querying
strategy or is it planned to support second "safe" one?

The JUnits failing in the overnight build are due to an NPE in an EditPart
provider class -->

java.lang.NullPointerException
at samplemodel.editor.VisualIDRegistry.getDiagramVisualID(VisualIDRegistry.java:26)
at samplemodel.edit.parts.EditPartFactoryImpl.createDiagramEditPart(EditPartFactoryImpl.java:67)
at samplemodel.edit.parts.EditPartFactoryImpl.createEditPart(EditPartFactoryImpl.java:47)
at samplemodel.providers.SampleModelEditPartProvider.createEditPart(SampleModelEditPartProvider.java:83)
at samplemodel.providers.SampleModelEditPartProvider.provides(SampleModelEditPartProvider.java:124)
at org.eclipse.gmf.runtime.diagram.ui.services.editpart.EditPartService$ProviderDescriptor.provides(EditPartService.java:95)

The diagram core runtime team owns the test, but we don't own the class
that is causing the NPE.  Can whoever owns the SampleModelEditPartProvider
take at look at this failure? 

Thanks, 

Steve.
