> Key: LUCENE-8642
> URL: https://issues.apache.org/jira/browse/LUCENE-8642
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Dawid Weiss
> Assignee: Dawid Weiss
> Priority: Minor
> Fix For: master (9.0)
>
>
> We have a silent fall-through on catch clause there if a field is inaccessible. This causes all collections to not be recursively descended into.
> We could hack it so that collection objects are counted "manually". Or we could propagate illegal access exception from ram tester, detect which tests/ objects do try to measure collection objects and either remove them (if it's not possible to measure accurately) or change them (if it is possible to estimate the size in a different way).
> Looking for feedback on this one.
