Hi, I was trying to install JBoss Tools in Eclipse Luna.

I have manually added at new software source, providing this url:

http://download.jboss.org/jbosstools/updates/stable/luna/

I have selected only this component:

{{ JBossAS Tools 3.0.1.Final-v20141209-0156-B106}}

And the installation process failed due to this error

An error occurred while collecting items to be installed
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

java.lang.NullPointerException
