Steve Ebersole commented on HHH-4625:
-------------------------------------
BTW, I found what we believe is the explanation for the failures being so intermittent
and difficult to reproduce. I forget the exact details, but it had to do with Javassist
using a weak reference to keep track of classloaders. Whatever change I made in the
injection plugin forced Javassist to hold the classloader reference. For whatever reason
on my system running the build never resulted in a GC that required reaping that above
mentioned weakref while on other systems it did sometimes.
Use of maven-injection-plugin intermittently leads to build failures
