----------------------------------

             Summary: StandaloneWalRecordsIterator may throw NPE if compressed WAL segment is empty
                 Key: IGNITE-8572
                 URL: https://issues.apache.org/jira/browse/IGNITE-8572
             Project: Ignite
          Issue Type: New Feature
          Components: persistence
            Reporter: Ivan Rakov
            Assignee: Ivan Rakov
             Fix For: 2.6


In case ZIP archive with WAL segment doesn't contain any ZIP entries, attempt to iterate through it with standalone WAL iterator will throw NPE:
{noformat}
Caused by: java.lang.NullPointerException

We should throw excpetion with descriptive error message instead.
