Markus Heiden commented on SOLR-7803: ------------------------------------- This problem looks like LUCENE-5573 > Classloading deadlock in TrieField > ---------------------------------- > > Key: SOLR-7803 > URL: https://issues.apache.org/jira/browse/SOLR-7803 > Project: Solr > Issue Type: Bug > Affects Versions: 5.2.1 > Environment: OSX > Reporter: Markus Heiden > Priority: Critical > Labels: patch > Attachments: TrieField.patch > > > When starting a test Sol instance, it locks up sometimes. We took a thread > dump and all threads are trying to load classes via Class.forName() and are > stuck in that method. One of these threads got one step further into the > <clinit> of TrieField where it creates an internal static instance of > TrieDateField (circular dependency). I don't know why this locks up exactly, > but this code smells anyway. So I removed that instance and made the used > methods static in TrieDateField. > This does not completely remove the circular dependency, but at least it is > no more in <clinit>. For the future someone may extract a util class to > remove the circular dependency. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
