[Fred Bricon (JIRA)]

     [ https://issues.jboss.org/browse/JBIDE-10836?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Fred Bricon updated JBIDE-10836:
--------------------------------

    Steps to Reproduce: 
Reproducible only with *Project Explorer*
1.Open a new clean workspace
2.make sure the JAXRS Maven configurator is enabled (Eclipse > Preferences > JBoss Tools > JBoss Maven Integration > JAX-RS facet) 
3.create new Dynamic Web Project, activate Jboss Maven Integration Facet, don't set any runtime
4.add dependency to pom (jaxrs-api or jersey), save pom
3.Context Menu -> Update Project Configuration, press OK

Exception is thrown.

When JAX-RS Facet is disabled (#2), no exception is thrown.

           Component/s: Webservices


I *think* that, at some point, the JAX-RS UI plugin must return a null value instead of an empty array in a viewer.

Assigning to Xavier for investigation.
