IonReader.next() throws NPEs for some invalid content #437
Description
(note: issue found by OSS-Fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=65452)
Looks like IonReader.next() leaks NullPointerExceptions (in addition to index-out-of-bounds and AssertionErrors), so it will be necessary to catch and re-throw those as well.
