I just tried it out and sometimes got this error halfway through a build:
Exception in thread "pool-101-thread-2"
java.lang.ArrayIndexOutOfBoundsException: 10
at java.util.ArrayList.add(ArrayList.java:352)
at
org.apache.maven.artifact.resolver.DefaultArtifactResolver$ResolveArtifactTask.resolveArtifact
(DefaultArtifactResolver.java:400)

org.apache.maven.artifact.resolver.DefaultArtifactResolver$ResolveArtifactTask.run

ThreadPoolExecutor.java:885)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(
ThreadPoolExecutor.java:907)
at java.lang.Thread.run(Thread.java:619)
The exact location and the array index changed, but the stacktrace was
always the same.
