Dominik Stadler created XMLBEANS-641:
----------------------------------------
Summary: Fuzzing XMLBeans triggers an assert() for an input-file
via Apache POI
Key: XMLBEANS-641
URL: https://issues.apache.org/jira/browse/XMLBEANS-641
Project: XMLBeans
Issue Type: Bug
Reporter: Dominik Stadler
Fuzzing Apache POI via oss-fuzz shows the following assert() being triggered
via an input-file.
Would be good to convert to IllegalArgumentException or IllegalStateException
so that fuzzy testing can continue to flag other places where assert() is used
incorrectly.
