Andy Webb updated SOLR-14252:
-----------------------------
Description:
The {{getMax}} and {{getMin}} methods in
[AggregateMetric|https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/metrics/AggregateMetric.java]
can throw an NPE if non-{{Number}} values are present in {{values}}, when it
tries to cast a {{null}} {{Double}} to a {{double}}. We've seen the values
{{false}}
PR: [https://github.com/apache/lucene-solr/pull/1247]
The patch adds a warning for non-{{Number}} values - we've seen it report {{not
a Number: false}} and {{not a Number: LocalStatsCache}} - so the NPE may have
been hiding other issues with metrics gathering, which warrant further
investigation.
