Summary: BytesTermAttributeImpl.copyTo NPEs when the BytesRef is
null
Key: LUCENE-6976
URL: https://issues.apache.org/jira/browse/LUCENE-6976
Project: Lucene - Core
Issue Type: Bug
Reporter: David Smiley
Assignee: David Smiley
Priority: Minor
The BytesTermAttributeImpl class, not used much I think, has a problem in its
copyTo method in which it assumes "bytes" isn't null since it calls
BytesRef.deepCopyOf on it. Perhaps deepCopyOf should support null? And also,
toString(), equals() and hashCode() aren't implemented but we can do so.
This was discovered in SOLR-8541; the spatial PrefixTreeStrategy uses this
attribute and the CachingTokenFilter when used on the analysis chain will call
clearAttributes() in it's end() method and then capture the state so it can be
replayed later. BytesTermAttributeImpl.clear() nulls out the bytes reference.
