Marek Novotny updated JBSEAM-5103:
----------------------------------
Steps to Reproduce:
Use seam example : <seam examples>/seamspace
1. Set 60 sec to the concurrent-request-timeout in components.xml.
{noformat}<seam examples>/seamspace/resources/WEB-INF/components.xml
19: <core:manager conversation-timeout="120000"
20: concurrent-request-timeout="60000"
21: conversation-id-parameter="cid"/>
{noformat}
2. Add a sleep process to ProfileAction.getMemberBlogs() method.
{noformat}<seam examples>/seamspace/src/org/jboss/seam/example/seamspace/ProfileAction.java
77: /**
78: * Used to read all blog entries for a member
79: */
80: @SuppressWarnings("unchecked")
81: @Factory("memberBlogs")
82: public void getMemberBlogs()
83: {
+ try{
+ System.out.println("-- sleep start");
+ Thread.sleep(10000L);
+ System.out.println("-- sleep end");
+ }catch(Exception e){}
84: if (name == null && authenticatedMember != null)
85: {
86: name = authenticatedMember.getMemberName();
87: }
88:
89: memberBlogs = entityManager.createQuery(
90: "from MemberBlog b where b.member.memberName = :memberName order by b.entryDate desc")
91: .setParameter("memberName", name)
92: .getResultList();
93: }
{noformat}
3. Execute 'mvn install;cd seamspace-ear;mvn jboss-as:deploy' command on the <seam examples>/seamspace directory.
4. Start JBoss AS server.
5. Move to 'http://localhost:8080/seam-space/home.seam' with web browser.
6. Login (demo/demo) -> [Create new blog entry]
7. Push the [Add entry] button (You can confirm '-- sleep start' message on stdout) and push the F5 button immediately.
8. You can confirm waiting of the F5 request[1] even if a sleep process has completed and occurring exception[2] after the concurrent-request-timeout.

> URL: https://issues.jboss.org/browse/JBSEAM-5103
> Project: Seam 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.3.0.Final
> Reporter: Eiichi Nagai
> Assignee: Marek Novotny
> Fix For: 2.3.1.CR1
>
>
> ConversationEntry after @End method process is removed by endRequest[1] process and does not release lock. Therefore, when there is a request duplicate with the same Conversation ID by F5 operation etc, since a lock is not released, the request has to wait till the concurrent-request-timeout even if pre-request is already completed.
