Erick Erickson commented on LUCENE-9080:
----------------------------------------
Yep. I didn't change any of these manually, all those changes are the result of
running regenerate and would require manual changes after the regenerate. The
only Java file I changed was generateUTR30DataFiles.java, and that to just to
use the new URL and version.
I can go through the generated code and put them back if that's indicated, I'm
just not all that enthused about manually editing all the files that say "DO
NOT EDIT" ;)

> Key: LUCENE-9080
> URL: https://issues.apache.org/jira/browse/LUCENE-9080
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Erick Erickson
> Assignee: Erick Erickson
> Priority: Major
> Attachments: after_regen.patch, before_regen.patch, status.res
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The root cause is that RamUsageEstimator.NUM_BYTES_INT has been removed and
> the python scripts still reference it in the generated scripts. That part's
> easy to fix.
> Last time I looked, though, the regenerate produces some differences in the
> generated files that should be looked at to insure they're benign.
> Not really sure whether this should be a Lucene or Solr JIRA. Putting it in
> Lucene since one of the failed files is:
> lucene/core/src/java/org/apache/lucene/util/packed/Packed8ThreeBlocks.java
> I do know that one of the Solr jflex-produced file has an unexplained
> difference so it may bleed over.
> "ant regenerate" needs about 24G on my machine FWIW.
