-----------------------------------
Summary: Infinite loop in NetworkServerControlImpl when reply >=
32k
Key: DERBY-6456
URL: https://issues.apache.org/jira/browse/DERBY-6456
Project: Derby
Issue Type: Bug
Components: Network Server
Affects Versions: 10.10.1.1
Reporter: Martin JANDA
When size of reply in NetworkServerControlImpl equals to 32k (max size for
short) ensureDataInBuffer is in infinite loop. clientIs.read(...,
replyBuffer.length - replyBufferCount) return 0 because 'replyBuffer.length -
replyBufferCount' is 0 (bytes to read).
Steps to reproduce:
Open many connections (for me 34) with at least 1 SELECT query. and call
getRuntimeInfo(). Runtime info string.length > 32kB. Leading to infinite loop.
