Hi,
As validation framework nicely supports OCL, following the tutorial for
validation framework in emf, I tried to implement a simple constraint with
my two plugins GeneratedOETests and helloworld. helloworld contributes the
context, binding and constrain in its plugin.xml:
<extension
point="org.eclipse.emf.validation.constraintBindings">
<clientContext
default="false"
id="com.acme.orderentry.constraintsContext">
<selector
class="helloworld.actions.ValidationDelegateClientSelector"/ >
</clientContext>
<binding
context="com.acme.orderentry.constraintsContext"
category="com.acme.orderentry.constraints"/>
</extension>
<extension
point="org.eclipse.emf.validation.constraintProviders">
<category
name="OrderEntry Constraints"
id="com.acme.orderentry.constraints"/>
<constraintProvider cache="true">
<package namespaceUri="http:///orderentry.ecore"/>
<constraints categories="com.acme.orderentry.constraints">
<constraint
lang="Java"
class="helloworld.actions.NonEmptyNamesConstraint"
severity="ERROR"
mode="Batch"
name="Non-Empty Names"
id="com.acme.orderentry.constraints.NameNotEmpty"
statusCode="1">
<description>
All customers should have some unique identifier or name.
</description>
<message>
A {0} has been found to have no unique identifier (name
or title).
</message>
<target class="Customer"/>
</constraint>
</constraints>
</constraintProvider>
</extension>
In GeneratedOETests which depend on helloworld, the plugin-test
BatchValidator does the following:
Customer customer=OrderEntryFactory.eINSTANCE.createCustomer();
ValidationDelegateClientSelector.running = true;
IBatchValidator validator =
(IBatchValidator)ModelValidationService.getInstance()
.newValidator(EvaluationMode.BATCH);
validator.setIncludeLiveConstraints(true);
IStatus status=validator.validate(customer,null);
ValidationDelegateClientSelector.running = false;
Collection descs=ConstraintRegistry.getInstance().getAllDescriptors();
logger.debug("desc size:"+descs.size());
Collection
contexts=ClientContextManager.getInstance().getClientContext s();
logger.debug("contexts size:"+contexts.size());
In validator.validate(customer,null), when the class loader tries to load
ValidationDelegateClientSelector, it gives java.lang.CircularityError
error. Before trying to load the ValidationDelegateClientSelector, the
class loader actually looks at whether it has been alrady loaded and it
fails to find the class altough we already used it before calling the
validator.validate(customer,null) method.
I am using eclipse 3.2.0
I had spent quite some time on this. I would appreciate any directions or
suggestions for workarounds.
Thanks,
Selcuk

Hi Selcuk,
Do you have a stack trace for the CircularityError?
Thanks,

From looking at the stack trace and this bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=5875, I am guessing that
something like the following is happening:
1. ValidationDelegateClientSelector resides in PluginB. An action in
PluginA calls the following line (which is line
WorkingsetActionBarContributor.java:137 in the stack trace below).
ValidationDelegateClientSelector.running = true;
2. During initialization of ValidationDelegateClientSelector, the osgi
loader loads the EMFModelValidationPlugin because
ValidationDelegateClientSelector implements
org.eclipse.emf.validation.model.IClientSelector.
3. During initialization of EMFModelValidationPlugin,
EMFModelValidationPlugin.configureConstraintBindings finds that
ValidationDelegateClientSelector is defined in the constraint bindings,
and so attempts to load ValidationDelegateClientSelector.
4. ValidationDelegateClientSelector is already being initialized from
step 1, and so throws java.lang.ClassCircularityError.
I have gotten around this for now by forcing EMFModelValidationPlugin to
load before ValidationDelegateClientSelector.running is called.
Is there something else I should be doing to avoid this problem?
Thanks,

Hi Chris,
the stack trace returns null. When I debug, I actually get a
ClassNotFoundError but when I dig in I can see that the class loader
returns circularity error.
One thing I tried was to remove the dependency on helloworld from
GeneratedOETests. I made the latch ValidationDelegateClient return true
always. This time the class loader successfully loaded the class and
everything went fine.
Thanks,
Selcuk

Hi Selcuk,
I have seen ClassCircularityError thrown in eclipse before and they were
caused by the plugin activator class trying to load a class that is in a
plugin that is already in the process of loading.
We found that the best way to avoid this problem is to avoid static
initializers in classes and avoid adding code to the start() method in
plugin activator classes.
In this case, I'm not seeing how the circularity could be formed because
the ValidationDelegateClientSelector should have to be loaded prior to
the validator.validate() call. Any chance you could set a breakpoint on
the ClassCircularityError constructor(s) and provide the stack? Calling
e.printStackTrace() after the error is constructed should provide the
stack on the console.
Thanks,
Chris
