Incomplete configuration file causes OutOfMemoryException
---------------------------------------------------------
Key: TIKA-866
URL: https://issues.apache.org/jira/browse/TIKA-866
Project: Tika
Issue Type: Bug
Components: config
Affects Versions: 1.0
Reporter: Stephan Mühlstrasser
Priority: Minor
I tried to override a built-in parser according to the method described in
issue TIKA-527. During testing this approach I used an incomplete configuration
file (as far as I learned from a discussion on the mailing list also mimetypes
and a detector should be specified):
$ cat tika-config.xml
<properties>
<parsers>
<parser class="org.apache.tika.parser.DefaultParser"/>
</parsers>
</properties>
Using this configuration file causes an OutOfMemoryException:
$ java -Dtika.config=tika-config.xml -jar tika-app-1.0.jar --list-parsers
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit
exceeded

Expected behavior: If the configuration file is not valid, and appropriate
exception should be produced.
