> Key: MNG-5981
> URL: https://issues.apache.org/jira/browse/MNG-5981
> Project: Maven
> Issue Type: Bug
> Components: Plugins and Lifecycle
> Affects Versions: 3.3.1, 3.3.3, 3.3.9
> Reporter: Stuart McCulloch
> Assignee: Christian Schulte
> Fix For: needing-scrub-3.4.0-fallout
>
>
> A user reported seeing NPEs when running a particular project in parallel:
> http://www.mail-archive.com/users%40felix.apache.org/msg17072.html
> This was tracked down to the way we defer lifecycle activation for components
> (potentially) involved in dependency injection cycles (A->B->A). This bug is
> only triggered by specific lookup sequences when running parallel builds.
> The key fix was to move when we start cycle detection to the first scoped
> component in the lookup: https://bugs.eclipse.org/bugs/show_bug.cgi?id=487090
> (since a cycle can only ever involve scoped components - unscoped/per-lookup
> components can never repeat)
> The accuracy was also improved by using {{Scopes.isCircularProxy}} to spot
> when we inject a circular dependency proxy (which is when when we need to
> defer activation until the end of the cycle to allow that proxy to be
> populated). Previously the code was overly pessimistic when considering what
> might end up as a cycle.
> Sisu 0.3.3 contains both these fixes:
> https://wiki.eclipse.org/Sisu/Changelog#Release_0.3.3
> Previous releases can be patched by replacing the old org.eclipse.sisu.inject
> and org.eclipse.sisu.plexus jars with the ones from the 0.3.3 release.
