In Doxygen 1.11.0 for Java, a class is displayed twice on class diagram #11024

Open tkaken opened 1 month ago

tkaken commented 1 month ago

Describe the bug

In Doxygen 1.11.0 for Java, a class is displayed twice on the class diagram. This makes the diagram cluttered and will not scale well.

Note that this might be limited to happening when there is a dependency cycle among the classes.

Screenshots

Here are the class diagrams generated using Doxygen 1.11.0. In each case, the twice displayed class is circled.

Doxygen1_11_0_ClassDiagramWithRepeatedClass

Doxygen1_11_0_ClassDiagramWithClass2Repeated

Here are the class diagrams generated from the same code using Doxygen 1.9.1. In these class diagrams, the circled class is shown just once.

To Reproduce

Source code

Here are the source files used.

// File: Class1a.java
package pkg1;

import pkg2.Class2;

public class Class1a {
    public Class1a()
    {
        this.theClass1b = new Class1b();
        this.theClass2 = new Class2();
    }

    public void useClass1b()
    {
        this.theClass1b.doClass1bStuff();
    }

    public void useClass2()
    {
        this.theClass2.doClass2Stuff();
    }

    private Class1b theClass1b;
    private Class2 theClass2;
}
//File: Class1b.java
package pkg1;

public class Class1b {

    public void doClass1bStuff() {
    }
}
//File: Class2.java
package pkg2;

import pkg1.Class1a;

    }

import pkg1.Class1a;

public class Class3 {

Files to reproduce the issue

Here is a zip file containing the files you can use to reproduce the issue.

Expected behavior

I expect each class to only be shown on the class diagram once as it was in version 1.9.1.

Version

I had this happen on version 1.11.0 on Windows 10, 64bit.

Additional context

The first version where this incorrect behavior started was in 1.9.2. It still is in 1.11.0 as shown above.

albert-github commented 1 month ago

I did some further bisection on the problem and it looks like:

ab483cd3ba39614dacc4f4e3901ac1cf76d413ca is the first bad commit

commit ab483cd3ba39614dacc4f4e3901ac1cf76d413ca

Date:   Mon Jan 11 13:56:35 2021 +0100

    bug_560861 Class graph does not differentiate same classes in different namespace

    The checking should not take place on the display name of the class but on its full name.

So looks like a bit of a difference between C++ and Java.
