User Comments:
jkovalsky: After testing first JUnit suite on Java application I wanted to create a new Ant based web application. After selecting Java Web > Web Application project type and pushing "Next >" button, IDE threw this exception and Ergonomics started to activate JavaEE and Wed functionality.

Uninstalled "All in one" version of Dev build, along with home and installation directory.
Downloaded and installed "Java SE" Dev version of IDE, from same day.

Launched IDE,.. installed c/c++ support module from plugins manager. (IDE restarted for changes to apply)

Went back to plugins managment, selected 3 plugins for installation (FindBugs, CVS, Tan UI theme), and clicked install.
Exception was thrown after accepting license and hitting next.

Delete the project and sources.
In the Plugins manager, Deactivate the JavaFX plugin. Restart the IDE.
Create a "Samples" JavaFX project "Advanced Media"
