             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.
