> ----------------------------------------------------------------------------------------
>
> Key: TIKA-3551
> URL: https://issues.apache.org/jira/browse/TIKA-3551
> Project: Tika
> Issue Type: Bug
> Components: config
> Affects Versions: 1.27, 2.1.0
> Reporter: Sebastian Nagel
> Priority: Major
> Fix For: 2.1.1
>
>
> The Tika configuration file parser exits with an exception when the XMLReaderUtils are configured in tika-config.xml without specifying all possible attributes, eg. without the attribute maxEntityExpansions (to use the default value):
> {noformat}
> <xml-reader-utils poolSize="20" />
> {noformat}
> There's a test whether the attribute value is null - however, [getAttribute()|https://docs.oracle.com/javase/8/docs/api/org/w3c/dom/Element.html#getAttribute-java.lang.String-] returns the empty string if the attribute is not present. The empty string then causes a NumberFormatException:
> {noformat}
