[jboss-jira] [JBoss JIRA] (JGRP-1598) STATE: broken

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1598?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12755504#comment-12755504 ] 

Bela Ban commented on JGRP-1598:
--------------------------------

The culprit was Draw: we use a BufferedOutputStream in DrawPanel.writeState(). This creates an internal buffer, which is flushed every 4096 bytes. This results in a message being sent to the state requester. *However* the buffer passed to the message is a *reference* to the internal buffer in BufferedOutputStream, and since this is modified again, the buffer in the message also changes !
The solution was to copy the buffer into the message in STATE$StateOutputStream.sendMessage().

> When receiving state, STATE fails to correctly push the state to the receiver. There is probably a bug in BlockingInputStream, as the state itself is transferred correctly.
> STATE_TRANSFER and STATE_SOCK are not affected
