Interesting, I haven't seen the automatic upgrade fail yet. Perhaps
running the second step (3.5.0 -> 4.10.2 using the 4.10.2 jar)
manually, too, will reveal what the problem is.
1) Anyway, I didn't check how sophisticated the upgrade logic is. You
seem to have only upgraded one of the cores manually (1.3.0 -> 3.5.0).
Either upgrade them all manually or upgrade them all automatically.
2) Try to run Maven with debug flags
3) Download lucene-core-4.10.2.jar manually and run IndexUpgrader and
CheckIndex on your index version 3.5.0 to complete the second step.
4) If all else fails, assuming it's really a memory / index size issue
(but I don't think it is), you could shard the statistics core with
DSpace 3.x (Solr 3.5.0) and try to upgrade each shard individually
(auto-upgrade of all shards at once should work, too, but I'm not
certain).
