TupleProtocol#writeBitSet unintentionally writes a variable length byte array
-----------------------------------------------------------------------------

                 Key: THRIFT-1365
                 URL: https://issues.apache.org/jira/browse/THRIFT-1365
             Project: Thrift
          Issue Type: Bug
          Components: Java - Compiler, Java - Library
            Reporter: Bryan Duxbury
            Assignee: Bryan Duxbury
             Fix For: 0.8


BitSet.length() only returns the highest-set-bit, meaning that if you have more 
than 8 optional fields, and the 9+th optional field is unset, then only the 
first byte's worth of bits will be serialized. This leads to a problem on the 
read side, where the bit vector is assumed to be fixed width, and arbitrary 
deserialization occurs.
