Unable to upgrade Lucene 6.x index using IndexUpgrader

[Henrik B A]

I'm trying to upgrade a index from Lucene 6.x to 7.x, and then to 8.x,
using IndexUpgrader [1].  But it never successfully upgrades to 7, and I
cannot figure out why.

I've also tried using CheckIndex [2] with the -exorcise option to fix the
index first, but that doesn't help.

Any ideas?  I've added console output at the end of this mail.

Cheers,
Henrik
