Comment 2 Jesse Glick 2010-09-27 08:25:28 UTC 
Easily reproducible just by trying to open any artifact from Maven Repository Browser. Regression perhaps from use of Aether? RepositorySystemSession is null, because DefaultMavenProjectBuilder.injectSession gets null from legacySupport.getSession() (I think).
Comment 3 Jesse Glick 2010-09-27 08:32:57 UTC 
core-main #659b3c8a50b2
Comment 4 Jesse Glick 2010-10-08 13:53:04 UTC 
core-main #115ceec52ac5 has a fix for a related exception when trying to view the dependency graph for a project.
Comment 5 Quality Engineering 2011-03-09 05:35:58 UTC 
Integrated into 'main-golden', will be available in build *201103090000* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main/rev/e0f7845ef448
User: Jesse Glick <jglick@netbeans.org>
Log: Another Aether NPE like #195045, #190588, and others.
Providing a utility method to fix this more simply. Cannot be fully automatic since it must be done in the active thread.
