(see bug 311283)

The actions which are enabled in the Navigate menu like Open Implementation, Open Hyperlink, Open Super Implementation .. should work as on normal Java files instead of throwing an error dialog.

Steps:
1. create a Java project with 'src' as source folder (default out of the box)
2. create file 'Test.java' in the project (not in 'src' folder) with this: 
import java.util.HashMap;

public class Test {

    void foo() {
        bar();
    }

    private void bar() {
        HashMap m= new HashMap();
        m.isEmpty();
    }
}

Place the caret on Hashmap and invoke Open Implementation (or other commands mentioned above) 
=> Throws a "Cannot Perform Operation" dialog


The commands are enabled in the context menu as well as in Navigate menu but we do a check when we run the action ActionUtil.isProcessable(..) which immediately throws a dialog when the resource is not on the build path even though we could go ahead and do the required action on the element. The fix would be to remove this check which is unnecessary similar to what was done for OpenAction.

We need to check the behaviour of the other Open actions (Open Call Hierarchy, Open Type Hierarchy...) and disable the actions that do not work as expected in all places.
