[jbosstools-issues] [JBoss JIRA] (JBIDE-13321) NPE from JBoss Maven tools

[Fred Bricon (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-13321?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12744293#comment-12744293 ] 

Fred Bricon commented on JBIDE-13321:
-------------------------------------

In that method, we check if the current project (the one we're installing the JAX-RS Facet to) is a child of an existing workspace project.

Well for some reason, for one of the potential parent projects, project.getLocation() returns null (which can happen, according to the API). So I believe Pete had a non-conventional project in his workspace at the time that bug occured. I have no idea how to reproduce though, all I can do is add a null-check for project.getLocation(), which is totally fine.
