Thank you! I was able to reproduce the problem you are experiencing and
used jmc to grab some stack traces while it is stuck spinning. They
all are some variant of this - the common bit being that we're always in
somewhere in POMReader:
"main" #1 prio=5 os_prio=0 cpu=133878.15ms elapsed=135.64s

So we're definitely in the maven-repo-helper code, entering via [1] and
stuck in [2]. Specifically, my guess is that we're looping in [3].
However, I haven't found a fix yet. I'm still picking through the pom files
in the patch to see if I can figure out why we're getting stuck. It
seems like the code expands the pom, it refers to itself (or otherwise
creates a cycle).
We can probably add some more debugging to maven-repo-helper too... :)
Cheers,
tony
