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

             Summary: SegmentTarWriter#readSegment does not check the return 
value of FileChannel#read
                 Key: OAK-7761
                 URL: https://issues.apache.org/jira/browse/OAK-7761
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: segment-tar
            Reporter: Michael Dürig
             Fix For: 1.10


We need to check the return value of {{FileChannel#read}} as that method might 
read fewer bytes than requested. The corresponding Javadoc is (hidden) at 
{{ReadableByteChannel#read}}: "A read operation might not fill the buffer, and 
in fact it might not read any bytes at all"
