[jboss-user] [JBoss Tools (users)] - JBossAS Tools causes NPE in Eclipse's Java Tooling

[NickDeGraeve]

I installed JBossTools 2.0.0.GA (JBossTools Core 2.0.0.GA, JBossAS Tools 1.0.0.GA & Hibernate Tools 3.2.0.GA) in Eclipse 3.3.1.1 via the Update Manager and URL http://download.jboss.org/jbosstools/updates/stable.

When I import an existing project into Eclipse I get NullPointerExceptions when the 'Java Tooling' initializes. If I disable the JBossAS Tools 1.0.0.GA component everything goes ok.

Any idea what goes wrong and how to fix it?


Thanks.

Nick.
