NullPointerException is Thrown when Using addClone Method in Java

LorenzoL · August 26, 2021, 10:18am

1. I copied the “C:\Windows\Fonts” folder somewhere else, and then tried to load it with

String [] dirs = {"D:\\Users\\KR45743\\Desktop\\myfonts"};
FontsLoader.loadExternalFonts(dirs);

I get the following exception:

Aspose slides version is: 21.8
Exception in thread “main” class com.aspose.slides.exceptions.ArgumentException: The specified path is empty
com.aspose.slides.internal.fx.catch.for(Unknown Source)
com.aspose.slides.internal.of.throws.int(Unknown Source)

at com.aspose.slides.FontsLoader.do(Unknown Source)
at com.aspose.slides.FontsLoader.loadExternalFonts(Unknown Source)
at com.mycompany.app.AsposeDebugging.main(AsposeDebugging.java:763)

I tried several names for the folder and I moved it to several locations, but the result is always the same.

2. I tried the code, and I get no errors. The output is quoted here below.

Aspose slides version is: 21.8

@LorenzoL,
Thank you for the additional information. I passed it to our development team. I will inform you of any progress.

andrey.potapov · August 26, 2021, 3:27pm

@LorenzoL,
“The specified path is empty” error is thrown in Aspose.Slides if a path to the font folder is empty. Please add a new folder to your project root folder (“fonts”, for example) and try to load fonts like this:

FontsLoader.loadExternalFonts(new String[] {"./fonts"});

If you get the same result, please share a simple standalone project with a code example reproducing the problem.

LorenzoL · August 27, 2021, 8:57am

@Andrey_Potapov I can confirm that the path to the font folder is NOT empty.
This is a program which reproduces the behaviour:

package com.mycompany.app;

import com.aspose.slides.FontsLoader;
import java.io.File;

public class AsposeDebugging4 {

    public static void main(String[] args) {
        String version = com.aspose.slides.License.getVersion();
        System.out.println("Aspose slides version is: " + version);

        String myPath = "D:/Users/KR45743/Desktop/fonts";
        File folder = new File(myPath);
        File[] files = folder.listFiles();
        System.out.println("Number of files = " + files.length);
        FontsLoader.loadExternalFonts(new String[]{myPath});

        System.out.println("End of the program");
    }
}

The output it produces is:

Aspose slides version is: 21.8
Number of files = 714
Exception in thread "main" class com.aspose.slides.exceptions.ArgumentException: The specified path is empty
com.aspose.slides.internal.fx.catch.for(Unknown Source)
com.aspose.slides.internal.of.throws.int(Unknown Source)
com.aspose.slides.FontsLoader.do(Unknown Source)
com.aspose.slides.FontsLoader.loadExternalFonts(Unknown Source)
com.mycompany.app.AsposeDebugging4.main(AsposeDebugging4.java:16)
	at com.aspose.slides.internal.fx.catch.for(Unknown Source)
	at com.aspose.slides.internal.of.throws.int(Unknown Source)
	at com.aspose.slides.FontsLoader.do(Unknown Source)
	at com.aspose.slides.FontsLoader.loadExternalFonts(Unknown Source)
	at com.mycompany.app.AsposeDebugging4.main(AsposeDebugging4.java:16)

Process finished with exit code 1

@LorenzoL,
We are sure that the problem is specific to your app environment. Please check the relative path as shown above for investigating this case and share the results. This can clarify the access problem. If the issue persists, please share the simple standalone project.

LorenzoL · August 27, 2021, 10:34am

I put the “fonts” directory inside the project and tried to load it with

FontsLoader.loadExternalFonts(new String[] {"./fonts"});

Nothing changes, I still get the same error “The specified path is empty”
You can find a mini project reproducing the problem here Dropbox - my-app.zip - Simplify your life

Because I am forbidden from copying fonts out of the system because of (idiotic) company rules, the ./fonts directory is empty. In any case, I get the error message “The specified path is empty” whether the directory is empty or not, so I don’t think the problem is with the font files themselves.
NB On my home system (Windows 10) the project runs flawlessly with this output:

Aspose slides version is: 21.8
Number of files = 0
End of the program

On my work system (the one I really care about) it raises com.aspose.slides.exceptions.ArgumentException as described in my previous messages.
If standard Java can access the folder without problems, why aspose can’t?

andrey.potapov · August 27, 2021, 4:47pm

@LorenzoL,
Thank you for the project example. I was unable to reproduce the error. I passed the project to our development team to investigate further. I will inform you of any progress.

andrey.potapov · August 30, 2021, 5:04pm

@LorenzoL,
Our development team has prepared a special build for you. This build contains an experimental fix to investigate the problem on your side. Please use it and share your results:

LorenzoL · September 10, 2021, 4:38pm

@Andrey_Potapov Thanks a lot for the new library and sorry for the late reply.
Using it the Exceptions in my small test programs do go away, so that is a very good sign! Alas, the real (large) application still crashing during the production of the PowerPoint file. I’ll identify where the problem now is and I’ll report back.

andrey.potapov · September 10, 2021, 5:23pm

@LorenzoL,
Thank you for your news. We will wait for the results.
