----------------------------------
Summary: PhoneticFilterFactory threadsafety bug
Key: SOLR-3424
URL: https://issues.apache.org/jira/browse/SOLR-3424
Project: Solr
Issue Type: Bug
Components: Schema and Analysis
Affects Versions: 3.6, 4.0
Reporter: David Smiley
Assignee: David Smiley
Priority: Minor
Fix For: 4.0
PhoneticFilterFactory has a static HashMap registry mapping an encoder name to
an implementation. There is a ReentrantLock used when the map is modified (when
the encoder config specifies a class name). However, this map, which can be
accessed by multiple indexing threads, isn't guarded on any of the reads, which
isn't just the common path but also the error messages which dump the registry
into the error message.
I realize the likelihood of a problem is extremely slim, but a bug's a bug.
