Incorrect label for "Make type XY abstract" mouse hover quick fix

For the following example code

    public interface IResolver {
        public void resolve();
    }

    public class SomeResolver implements IResolver {		
    }

Quick fix assistant complains "The type SomeResolver must implement the inherited abstract method IResolver.resolve()".

It offers two quick fixes on Ctrl-1:
* "Add unimplemented methods"
* "Make type 'SomeResolver' abstract"

But for mouse hovered quick fixes it incorrectly renders text of "Make type 'SomeResolver' abstract" only as ""Make type 'SomeResolver'".

See attached screenshot.

I have this JDT feature installed (Kepler 4.3, About / Installation Details):

  Eclipse Java Development Tools
  3.9.0.v20130605-2000

I don't know if it's a problem only in Linux, because I can't reproduce this with Windows. Moving to JDT/UI for investigation.

Cannot reproduce it on Windows and Lubuntu 12.04 with Eclipse 4.3.
Please provide your OS and Java version details. 
Also, check for any exceptions in the log on hovering.

Also doesn't reproduce on my Ubuntu 12.04 with "Ubuntu 11" font.

Looks like this is a problem in the Link widget with your specific font.
What's your "Javadoc dialog font" on the "Colors and Fonts" preference page?


The Link controls are created here, but we don't restrict their width:
org.eclipse.jdt.internal.ui.text.java.hover.AbstractAnnotationHover.AnnotationInformationControl#createCompletionProposalLink(Composite, ICompletionProposal, int)

Sorry, this is about the "Dialog font".

Markus, you were right - if I change dialog font to any other from "Ubuntu", then tooltip quick fix texts are rendered properly.

Ubuntu font is default font (I've never change dialog font before) and also is set to it when you press "Use System Font" button.

I'm running vanilla fresh Ubuntu 13.04 32bit with OpenJDK 1.7.0_21-b02.

$ uname -a
Linux pc-libor 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:30 UTC 2013 i686 
i686 i686 GNU/Linux

$ java -version
java version "1.7.0_21"
OpenJDK Runtime Environment (IcedTea 2.3.9) (7u21-2.3.9-1ubuntu1)
OpenJDK Server VM (build 23.7-b01, mixed mode)

Eclipse installation details from About dialog are attached.

Thanks, so it looks like a general problem with calculating the width of the "Ubuntu" font in Ubuntu 13.04.
