> It looks as thought there was a ticket to address this\[1\], but it appears 
> to not have completely addressed the issue. On an 0.6.1 instance (that 
> crashed hard), I'm getting a stack trace on startup indicating a corrupt prov 
> repo. The relevant part of the stack trace (unfortunately typed by hand, so 
> forgive the inevitable typos) is:
> {quote}
> ...
> Caused By java.lang.IllegalArgumentException: No enum constant 
> org.apahe.nifi.provenance.ProvenenceEventType.
> at java.lang/.Enum.valueOf...
> at 
> org.apache.nifi.provenance.ProvenanaceEventType.valueOf(ProvenanaceEventType.java:19)
> at
> org.apache.nifi.provenance.StandardRecordReader.nextRecord(StandardRecordReader.java:284)

> In 0.x HEAD, this appears to have moved a bit\[3\]. Same is true for 
> 1.x\[4\]. In both 0.x\[5\] and 1.x\[6\], code was added to check for "bad" 
> records coming from the reader, and skip them. However, this appears to only 
> address the issue if the corrupt / bad record is the *first* record coming 
> out of a reader. If it is a subsequent record, the corruption remains.
