Benjamin Bentmann updated MNG-3580:
-----------------------------------
Attachment: debug-output.patch
bq. I'm reopening this.
Any suggestions on how are we supposed to fix data corruption in a central
collection type like {{ArrayList}}?
I built a [custom Maven 2.0.9
distro|http://people.apache.org/~bentmann/maven/MNG-3580/] from the
corresponding
[tag|http://svn.apache.org/repos/asf/maven/components/tags/maven-2.0.9/] which
differs from the official distro only by the attached patch. The patch is
adding some debug output to stderr intended to track the point where the
offending null element in the {{ArrayList}} pops up. In case of harmony-629320,
this was the call to {{ArrayList.addAll(int, Collection)}} in
ModelUtils.java:243. Joakim, it would be interesting to see what debug logs you
get for IBM JDK 1.6.
