User Comments:
ytn01: I installed FCS build.
Started it,.. and upon prompt, imported settings from an existing NB 8.1 installation. (IDE started indexing Maven repostiories in the background)
Then, manually registered a Tomcat 8.0.36 installation I have.
Then, updated the Java DB configuration to point to a custom installation that I have.
Then switched to the projects window from Services window,.. and Exception got thrown.

GUEST: NPE clicking Properties in context menu on a Web Project.

I installed FCS build.
Started it,.. and upon prompt, imported settings from an existing NB 8.1 installation. (IDE started indexing Maven repostiories in the background)
Then, manually registered a Tomcat 8.0.36 installation I have.
Then, updated the Java DB configuration to point to a custom installation that I have.
Then switched to the projects window from Services window,.. and RIGHT CLICKED on a Java Web Project that was opened from last session.

and Exception got thrown. The RIGHT CLICK seems to be the triggering cause.

I meant to say,.. RIGHT CLICK and Click on Properties.

I've got the same NPE after created new Java Web Application project via wizard, not from existing sources. After project is created, attempt to open Project Properties throws the same NPE. Looks like FCS stopper
