Martijn van Groningen commented on LUCENE-7571:
-----------------------------------------------
The test failed doing a numeric join on a float point join field. Due to
precision loss when converting an integer to a float during indexing more
documents matched than was expected when testing the numeric join.
> TestJoinUtil.testSingleValueRandomJoin() failure
