Hans Uhlig updated FLUME-2074:
------------------------------
Description:
ResettableInputStream returns signed values( -128 - 127 ) when reading data,
specifically -1 when file stream contains 0xFF rather than unsigned data
(0-255) and negative control signals. This causes a premature EOF to be
detected by deserializers written to obey defined control signals.
ResettableInputStream.read() returns an integer and should be returning the
unsigned value of the byte (0 - 255) with -1 as en EOF rather than the signed
value of (-128 - 127).
was:
ResettableInputStream returns -1 when parsing binary stream 0xff which causes
deserializers using -1 to indicate EOF to truncate prematurely.
ResettableInputStream.read() returns an int and should be returning the
unsigned value of the byte (0 - 255) with -1 as en EOF rather than the signed
value of (-128 - 127).
