> I encountered a very similar situation as described in MNG-6737. 
> It happens when I want to find the transitive dependencies of the Artifact
> org.webjars.npm:babel-core:6.0.16
> I tried the Maven-goal dependency:tree on a Maven-Project with only this Artifact in the pom. 
> With Maven 3.6.3 I got a StackOverflowError (with a similar Stacktrace as below. The accept get repeated).
> With Maven 3.8.1 it took considerably longer and ended in an OutOfMemoryError (same Stacktrace).
> The same behaviour happens of course if I want to view the transitive dependencies of my 
> project in Eclipse.
> I also tried to calculate the transitive dependencies in java itself, and I found that the Threads are stuck in a stacktrace of the form:
>  
> {code:java}
> Thread [main] (Suspended) Stack<E>.get(int) line: 75
>  AbstractList$Itr.next() line: 358
>  Stack<E>(AbstractCollection<E>).contains(Object) line: 106 PathRecordingDependencyVisitor.visitEnter(DependencyNode) line: 99 DefaultDependencyNode.accept(DependencyVisitor) line: 343 DefaultDependencyNode.accept(DependencyVisitor) line: 347
>  
> (... omitted many Repititions...)
> DefaultDependencyNode.accept(DependencyVisitor) line: 347 NearestVersionSelector.newFailure(ConflictResolver$ConflictContext) line: 158 NearestVersionSelector.backtrack(NearestVersionSelector$ConflictGroup, ConflictResolver$ConflictContext) line: 120 NearestVersionSelector.selectVersion(ConflictResolver$ConflictContext) line: 93 ConflictResolver.transformGraph(DependencyNode, DependencyGraphTransformationContext) line: 180 
> ChainedDependencyGraphTransformer.transformGraph(DependencyNode, DependencyGraphTransformationContext) line: 80
> DefaultDependencyCollector.collectDependencies(RepositorySystemSession, CollectRequest) line: 273 DefaultRepositorySystem.collectDependencies(RepositorySystemSession, CollectRequest) line: 284
>      
> (..ommitted own code...)
> {code}
> I used:
> org.apache.maven:maven-resolver-provider:3.8.1
> org.apache.maven.resolver:maven-resolver-util:1.6.2
> I used ArtifactDescriptorPolicy.STRICT (maybe this setting makes a difference).
> So maybe it is not even a Bug, and it just happens that org.webjars.npm:babel-core:6.0.16 behaves a bit like a Zip-Bomb for Maven and there is nothing one can do here.
