Description

Here it fails because -verbose is not set:

$ java -cp ./lucene-core-4.4-SNAPSHOT.jar org.apache.lucene.index.IndexUpgrader ./INDEX
Exception in thread "main" java.lang.IllegalArgumentException: printStream must not be null
at org.apache.lucene.index.IndexWriterConfig.setInfoStream(IndexWriterConfig.java:514)
at org.apache.lucene.index.IndexUpgrader.<init>(IndexUpgrader.java:126)
at org.apache.lucene.index.IndexUpgrader.main(IndexUpgrader.java:109)

Here it works with -verbose set:

$ java -cp ./lucene-core-4.4-SNAPSHOT.jar org.apache.lucene.index.IndexUpgrader -verbose ./INDEX
