NullPointerException in TreeTaggerWrapper

[jzell]

What steps will reproduce the problem?
1. Simple test using the TreeTaggerWrapper (the environment is well configured with
the resources from here: http://www.cis.uni-muenchen.de/~schmid/tools/TreeTagger/):

import java.util.Calendar;
import java.util.Date;

import de.unihd.dbs.heideltime.standalone.DocumentType;
import de.unihd.dbs.heideltime.standalone.HeidelTimeStandalone;
import de.unihd.dbs.heideltime.standalone.OutputType;
import de.unihd.dbs.heideltime.standalone.POSTagger;
import de.unihd.dbs.heideltime.standalone.components.impl.TimeMLResultFormatter;
import de.unihd.dbs.heideltime.standalone.exceptions.DocumentCreationTimeMissingException;
import de.unihd.dbs.uima.annotator.heideltime.resources.Language;

public class HeidelTest {

    public static void main(String[] args)
        throws DocumentCreationTimeMissingException {

    final String configProps = "/config.props";

    String configPath = HeidelTest.class.getResource(configProps).getFile();

    HeidelTimeStandalone heidel = new HeidelTimeStandalone(Language.FRENCH,
        DocumentType.NEWS, OutputType.TIMEML, configPath,
        POSTagger.TREETAGGER);

    Date documentCreationTime = Calendar.getInstance().getTime();

    String result = heidel.process(
"samedi 13 décembre 2014 à 20h00.",
        documentCreationTime, new TimeMLResultFormatter());

    System.out.println(result);
    }

}

What is the expected output? What do you see instead?

java.lang.NullPointerException

What version of the product are you using? On what operating system?
HeidelTime 1.8 on Ubuntu 64

Please provide any additional information below.

Looking at the code in de.unihd.dbs.uima.annotator.treetagger.TreeTaggerWrapper class,
line 494:

 if ((!(token.getPos().equals(null))) &&
         (token.getPos().equals("EMPTYLINE"))){
         token.removeFromIndexes();
         }

token.getPos() cannot be compared to null by calling the equals method on it if it
is actually null...

So, the previous portion of code should be replaced by:

if (token.getPos() != null
            && token.getPos().equals("EMPTYLINE")) {
            token.removeFromIndexes();
        }

Hi and thanks for the report.

We actually fixed that exact issue in that exact way back in September (see re16ec31522e9)
and the code is part of the 1.8 release. Can you check whether your setup has an older
version of HeidelTime in its CLASSPATH?

I've tested your code and it works perfectly for me without modification in an Eclipse
project that has HeidelTime's 1.8 standalone .jar set as a library:

Ooohh, my mistake: I had the 1.7 release. Yet I downloaded it a few days ago only from
https://code.google.com/p/heideltime/wiki/Downloads ... Maybe I clicked on the links
for the old releases.

Sorry for the loss of time.

We released 1.8 on Monday and I think that's when we last edited that page, too. I guess
the download buttons could be more prominent, but we don't get a lot to work with in
terms of Wiki markup...

No worries.

If i'm not mistaken, the version in the pom.xml is still 1.7.

You're absolutely right. I'll have to repackage the kit.
