Description

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.
