[jbosstools-issues] [JBoss JIRA] (JBIDE-10016) NullPointerException in VPE when an attribute is intensively changed

[Yahor Radtsevich (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-10016?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12637132#comment-12637132 ] 

Yahor Radtsevich commented on JBIDE-10016:
------------------------------------------

*Note:* I did not review [^JBIDE-10016_20111025.patch] completely yet, but the following change seems to be redundant, since there is only one thread, and synchronization is not necessary:
{code:title=VpeController.java}
/**
 * @return the changeEvents
 */
public List<VpeEventBean> getChangeEvents() {
	if (changeEvents == null) {
-		changeEvents = new LinkedList<VpeEventBean>();
+		changeEvents = Collections.synchronizedList(new LinkedList<VpeEventBean>());
	}
	return changeEvents;
}
{code}
