Created by Denis Golovin from Crucible comment on SingleDeployableWorkspaceListener.java line 44 https://source.jboss.org/cru/REV-JBIDE-4#c157 :
Documentation for getDelta() says:
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
so potential NPE in this line
