[jboss-jira] [JBoss JIRA] (JGRP-1753) BlockingInputStream: reading beyond the array's capacity

Bela Ban created JGRP-1753: ------------------------------ Summary: BlockingInputStream: reading beyond the array's capacity Key: JGRP-1753 URL: https://issues.jboss.org/browse/JGRP-1753 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.4.2, 3.5 If a BlockingInputStream {{input}} has a capacity of 8000 and we're calling {{input.read(buf, 0, buf.length)}} on a user buffer of 10000 with 14000 bytes added to {{input}}, then the following can happen: * {{input}} reads the first 8000 bytes and copies them to the user's buffer * The write position for the user's buffer is now at 8000 and the max number of bytes to be added is 2000 bytes, even if we have another 6000 bytes ! * Instead of adding another 2000 bytes, we add another 6000 bytes, leading to an ArrayIndexOutOfBoundsException SOLUTION: the length of the remaining bytes has to be min(available, remaining space in user's buffer). The unit test is {{BlockingInputStreamTest.testWritingBeyondLength()}} -- This message is automatically generated by JIRA.
