Lucene error messages during tests ---------------------------------- Key: JBIDE-17285 URL: https://issues.jboss.org/browse/JBIDE-17285 Project: Tools (JBoss Tools) Issue Type: Bug Components: webservices Affects Versions: 4.2.0.Alpha2 Reporter: Xavier Coulon Assignee: Xavier Coulon Fix For: 4.2.0.CR1 The following errors appear in the build logs: {code} Exception in thread "Lucene Merge Thread #2" org.apache.lucene.index.MergePolicy$MergeException: org.apache.lucene.store.AlreadyClosedException: this Directory is closed at org.apache.lucene.index.ConcurrentMergeScheduler.handleMergeException(ConcurrentMergeScheduler.java:517) at org.apache.lucene.index.ConcurrentMergeScheduler$MergeThread.run(ConcurrentMergeScheduler.java:482) Caused by: org.apache.lucene.store.AlreadyClosedException: this Directory is closed at org.apache.lucene.store.Directory.ensureOpen(Directory.java:288) at org.apache.lucene.store.RAMDirectory.listAll(RAMDirectory.java:94) at org.apache.lucene.index.IndexFileDeleter.refresh(IndexFileDeleter.java:335) at org.apache.lucene.index.IndexWriter.merge(IndexWriter.java:3954) at org.apache.lucene.index.ConcurrentMergeScheduler.doMerge(ConcurrentMergeScheduler.java:388) at org.apache.lucene.index.ConcurrentMergeScheduler$MergeThread.run(ConcurrentMergeScheduler.java:456) {code} but the tests pass. Maybe using Lucene's SearcherManager (as shown on http://blog.mikemccandless.com/2011/09/lucenes-searchermanager-simplifies...) could fix the problem ?
