Uwe Schindler commented on LUCENE-7132:
---------------------------------------
bq. Dawid Weiss, Uwe Schindler - any idea what i did to causes this weird
AccessControlException in TestSimpleExplanations?
The problem is caused by the static leak detector (same issue like the fix I
posted to Solr). The leak detetctor measures static fields and their heap
usage. Unfortunately this fails for non-public classes (e.g. implementations of
Path). So be sure to null all static fields on afterClass().
In Java 9 this fails more often, so be sure to always null out static non-final
fields that point to "more complex" and internal Java objects.
> BooleanQuery scores can be diff for same docs+sim when using coord (disagree
> with Explanation which doesn't change)

> Some of the folks
> [reported|http://find.searchhub.org/document/80666f5c3b86ddda] that sometimes
> explain's score can be different than the score requested by fields
> parameter. Interestingly, Explain's scores would create a different ranking
> than the original result list. This is something users experience, but it
> cannot be re-produced deterministically.
