[jira] Created: (TIKA-239) System.err prints from XmlRootExtractor
System.err prints from XmlRootExtractor
---------------------------------------
Key: TIKA-239
URL: https://issues.apache.org/jira/browse/TIKA-239
Project: Tika
Issue Type: Bug
Components: parser
Reporter: Jukka Zitting
The XmlRootExtractor is often given non-XML files to look at, which causes the XML parser to fail with error messages. It looks like the default behaviour is to print some of these error messages to System.err, as shown below:
$ java -jar tika-app-0.4-SNAPSHOT.jar --text lucene-2.2.0-src.zip > /dev/null
java.io.EOFException

Tika should never print stuff to System.out or System.err unless explicitly instructed to do so.

Jukka Zitting resolved TIKA-239.
--------------------------------
Resolution: Cannot Reproduce
Not sure what we've changed related to this, but I can no longer reproduce this problem with Tika 0.6.
