> NPE in buildComposite() method of ConfigBase
> --------------------------------------------

> Key: TIKA-4586
> URL: https://issues.apache.org/jira/browse/TIKA-4586
> Project: Tika
> Issue Type: Bug
> Components: config
> Affects Versions: 3.2.2
> Reporter: Gus Heck
> Priority: Major
>
> I encountered the following stack trace today:
> {code:java}
> Caused by: java.lang.NullPointerException
> at
> org.apache.tika.config.ConfigBase.buildComposite(ConfigBase.java:144)
> at
> org.apache.tika.metadata.filter.MetadataFilter.load(MetadataFilter.java:47)
> at org.apache.tika.config.TikaConfig.<init>(TikaConfig.java:193)
> at org.apache.tika.config.TikaConfig.<init>(TikaConfig.java:170)
> at org.apache.tika.config.TikaConfig.<init>(TikaConfig.java:162)
> at
> org.jesterj.ingest.processors.TikaProcessor$Builder.configuredWith(TikaProcessor.java:178)
> {code}
> debugging reveals that getLocalName() is returning null here:
> {code:java}
> protected static <P, T> P buildComposite(String compositeElementName,
> Class<P> compositeClass,
> String itemName, Class<T> itemClass,
> Element properties)
> throws TikaConfigException, IOException {
> if (!properties.getLocalName().equals("properties")) {
> throw new TikaConfigException("expect properties as root node");
> } {code}
> Config file loading at the time was:
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
> <properties>
> <parsers>
> <parser class="org.apache.tika.parser.XMLParser">
> <mime>application/xml</mime>
> </parser>
> </parsers>
> </properties>
> {code}
> This is following an upgrade of tika version so there may be something
> non-conformant about that file, but probably an NPE is not the right way to
> express the problem even if the config is wrong.
