[seam-issues] [JBoss JIRA] (JBSEAM-5067) ConcurrentModificationException in ServerConversationContext.flush()
Andrey Zhemoytuk created JBSEAM-5067:
----------------------------------------
Summary: ConcurrentModificationException in
ServerConversationContext.flush()
Key: JBSEAM-5067
URL: https://issues.jboss.org/browse/JBSEAM-5067
Project: Seam 2
Issue Type: Bug
Components: Core
Affects Versions: 2.3.0.Final
Environment: JBoss AS 7.1.0.Final (JSF RI 2.1.5)
Reporter: Andrey Zhemoytuk
The exception fails after render response phase if long running conversation is active and
a bean in conversation scope (additions map) has either page scoped injection or
page/conversation/session scoped outjection.
The issue is not reproducible if http://java.net/jira/browse/JAVASERVERFACES-1685 is
reverted. Call to equals in com.sun.faces.context.SessionMap#put (lines 132-138)
introduced with 1685 fix causes injection/outjection to occur:
boolean doSet = true;
if (null != value && null != result) {
doSet = ! result.equals(value);
}
if (doSet) {
session.setAttribute(key, value);
}
