Description

If WAL archiver is disabled and WALRecord being logged has rollOver() == true, then log() call blocks forever in FileArchiver's method:

nextAbsoluteSegmentIndex:1707, FsyncModeFileWriteAheadLogManager$FileArchiver (org.apache.ignite.internal.processors.cache.persistence.wal)
access$3200:1437, FsyncModeFileWriteAheadLogManager$FileArchiver (org.apache.ignite.internal.processors.cache.persistence.wal)
pollNextFile:1384, FsyncModeFileWriteAheadLogManager (org.apache.ignite.internal.processors.cache.persistence.wal)
initNextWriteHandle:1243, FsyncModeFileWriteAheadLogManager (org.apache.ignite.internal.processors.cache.persistence.wal)
rollOver:1130, FsyncModeFileWriteAheadLogManager (org.apache.ignite.internal.processors.cache.persistence.wal)
log:712, FsyncModeFileWriteAheadLogManager (org.apache.ignite.internal.processors.cache.persistence.wal)

Reproducer is attached.
