> PLXCOMP-159 is responsible (confirmed by substituting patched JAR). I am not positive but I believe this is also the cause of a critical (if sporadic) error in the NetBeans embedder, starting to appear I think when RC1 was integrated (maybe RC2): https://netbeans.org/bugzilla/show_bug.cgi?id=190530
> PLXCOMP-158 is also related.
> Please consider producing a new release of plexus-interpolation containing these two patches and using it in Maven 3.0 RC3.
