[jbosstools-issues] [JBoss JIRA] (JBIDE-20700) JBoss Knowledge Base Builder hangs up

[Archimedes Trajano (JIRA)]

     [ https://issues.jboss.org/browse/JBIDE-20700?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Archimedes Trajano updated JBIDE-20700:
---------------------------------------
           Description: 
When loading up a multi-module Maven project with EAR, WAR and jar components on a fresh installation of Eclipse where the following have been added

* Tycho Project Configurator
* EclEmma
* JBoss Tools 4.3.0Beta2

I am getting Eclipse hanging on *Invoking JBoss Knowledge Base Builder*.  Clicking on cancel does not cancel the operation either.

The workaround is to disable the *JBoss Knowledge Base* in each WAR and JAR project.

  was:
https://community.jboss.org/message/833488

The cause is thread unsafe code in org.jboss.tools.jsf.jsf2.bean.model.impl.DefinitionContext. When one thread reads from HashSet while another modifies it, sometimes reading slips into eternal cycle. That is a feature of implementation of java.util.HashSet, and the only way to avoid it is to provide thread safety. I will open an issue.

         Fix Version/s:     (was: 4.2.0.Alpha1)
                            (was: 4.1.1.Alpha1)
    Steps to Reproduce: 
Use Eclipse from the installer and installed the Eclipse for JEE Developers

Installed 
* Tycho Project Configurator
* EclEmma
* JBoss Tools 4.3.0Beta2

Imported the following project and sub-projects https://github.com/trajano/jaspic-tester.

            Workaround: Workaround Exists
           Environment: 
Windows 10
JDK 8
Eclipse Mars
JBoss Tools 4.3.0beta2 (the one from marketplace)
     Affects Version/s: 4.3.0.Beta2
               Affects: User Experience
