capabilities preference page may not exist

[Bananeweizen]

The first link in your preferences goes to the capabilities preference. However capabilities are optional and not contained in many of the smaller Eclipse products/packages.

See https://wiki.eclipse.org/Eclipse/Capabilities for reference.

So for instance clicking the preference link in an "Eclipse IDE for Java Developers" package does not have any effect.

I'm not sure if you can package the capabilities stuff into your plugins to work around this.
