Problems comparing UML models. #23
Description
With Rosetta 1.0.3 and 1.0.5, one can install the following features:
UML2 Extender SDK 5.5.2.v20210228-1829 org.eclipse.uml2.sdk.feature.group Eclipse Modeling Project
UML2 Extender SDK Developer Resources 5.5.2.v20210228-1829 org.eclipse.uml2.sdk.source.feature.group Eclipse Modeling Project
Model comparison (EMF Compare) - UML2 support 3.3.14.202102231741 org.eclipse.emf.compare.uml2.feature.group Eclipse Modeling Project
With Rosetta 1.0.3, comparing two *.uml files works properly.
With Rosetta 1.0.5, this comparison brings up an internal error:
An internal error occurred during: "Computing Model Differences".
loader constraint violation:
when resolving method 'void org.eclipse.emf.compare.scope.FilterComparisonScope.setResourceSetContentFilter(com.google.common.base.Predicate)'
the class loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @7a8450a of the current class, org/eclipse/emf/compare/ide/ui/internal/logical/ComparisonScopeBuilder,
and the class loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @34347e00 for the method's defining class, org/eclipse/emf/compare/scope/FilterComparisonScope,
have different Class objects for the type com/google/common/base/Predicate
used in the signature
(org.eclipse.emf.compare.ide.ui.internal.logical.ComparisonScopeBuilder is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @7a8450a, parent loader 'platform';
org.eclipse.emf.compare.scope.FilterComparisonScope is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @34347e00, parent loader 'platform')
It turns out that there are differences between the two versions of Rosetta w.r.t Eclipse features.
In 1.0.3, the installation of the UML2 comparison feature looks like this:
This is consistent with the Rosetta 1.0.3 dependencies:
In 1.0.5, the Rosetta dependencies resolve to an earlier version of EMF Compare:
This affects the installation of UML2 compare:
The difference seems to be causing the runtime discrepancy between the versions of com/google/common/base/Predicate.
