Milos Kleint created MINDEXER-63:
------------------------------------
Summary: NullPointerException at
org.apache.maven.index.context.DefaultIndexingContext.acquireIndexSearcher
Key: MINDEXER-63
URL: https://jira.codehaus.org/browse/MINDEXER-63
Project: Maven Indexer
Issue Type: Bug
Affects Versions: 5.0.0
Environment: netbeans 7.3 dev builds.
Reporter: Milos Kleint
Priority: Critical
see issue http://netbeans.org/bugzilla/show_bug.cgi?id=219645
for some reason (unknown to me yet) the index files cannot be deleted. The
codebase then gets into bad state.
possibly wrong code in DefaultIndexingContext:
public synchronized void replace( Directory directory )
    throws IOException
  {
    final Date ts = IndexUtils.getTimestamp( directory );
    closeReaders();
    deleteIndexFiles( false );
    IndexUtils.copyDirectory( directory, indexDirectory );
    openAndWarmup();
    // reclaim the index as mine
    storeDescriptor();
    updateTimestamp( true, ts );
    optimize();
  }
when deleteIndexFiles(0 fails, openAndWarmup() is not called. also
closeReaders() ignores indexWriter..
