[Denis Golovin (Updated) (JIRA)]

     [ https://issues.jboss.org/browse/JBIDE-9677?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Denis Golovin updated JBIDE-9677:
---------------------------------

    Steps to Reproduce: 
EXEC: Install AS Module from update site on Eclipse SDK.
EXEC: Create Dynamic Web Project
EXEC: Create new empty xml file and mark it as deployable
EXEC: Close Project
ASSERT: No NullPointerExceptions reported in Error Log View

  was:
EXEC: Install AS Module from update site on Eclipse SDK.
EXEC: Create Project
EXEC: Close Project
ASSERT: No NullPointerExceptions reported in Error Log View



Still can replicate it for AS Tools installed on Eclipse SDK and the exception is:
{noformat}java.lang.NullPointerException
	at org.eclipse.wst.server.core.internal.Server.getModules(Server.java:2426)
	at org.jboss.ide.eclipse.as.core.modules.SingleDeployableFactory$UndeployFromServerJob.run(SingleDeployableFactory.java:454)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54){noformat}
The same scenario works for installation on Jave EE IDE, but closing the project removes file marked as deloyable from server view. Opening project doesn't restore state. I'm not sure is is an issue, but it takes time to realize that files marked as deployable should be marked again after reopening the project

> Documentation for getDelta() says:
> {quote}Returns a resource delta, rooted at the workspace, describing the set of changes that happened to resources in the workspace. Returns null if not applicable to this type of event.
> Returns:
> the resource delta, or null if not applicable{quote}
> so potential NPE in this line
