DDMReader readBytes ArrayIndexOutOfBoundsException
--------------------------------------------------
Key: DERBY-4088
URL: https://issues.apache.org/jira/browse/DERBY-4088
Project: Derby
Issue Type: Bug
Components: Network Server
Affects Versions: 10.4.2.0
Environment: CentOS 5, java 1.6.0_11
Reporter: Urban Widmark
DDMReader.readBytes(int length) checks the length vs
DssConstants.MAX_DSS_LENGTH, but ignores the fact that the buffer position
"pos" might not be 0. If pos is non-zero then the pos + length can be larger
than the size of "buffer" causing an ArrayIndexOutOfBoundsException.
For me this happened when sending a BLOB that was 32766 bytes long. The value
of pos was 2 in that method.
