This was triggered after decreasing commit interval to 30s to test other things, making this error more often. Stacktrace from master:

java.util.ConcurrentModificationException: null
        at java.util.TreeMap$PrivateEntryIterator.nextEntry(Unknown Source) ~[?:?]
        at java.util.TreeMap$EntryIterator.next(Unknown Source) ~[?:?]
        at java.util.TreeMap$EntryIterator.next(Unknown Source) ~[?:?]
        at dpf.sp.gpinf.indexer.process.IndexItem.saveMetadataTypes(IndexItem.java:228) ~[iped-engine-4.0.0-snapshot.jar:?]
        at dpf.sp.gpinf.indexer.process.Manager$1.run(Manager.java:542) ~[iped-engine-4.0.0-snapshot.jar:?]

I believe this can also happen in last 3.18.x versions.
