Create PDF of Live Script produces broken PDF file

I am running MATLAB 2017a, on a MacBook Pro (2017, 15"), under OS X 10.13.1. When I try to save a Live Script as PDF, I get about 1000 java errors. The PDF is still generated, BUT the PDF file is broken - Acrobat will not open it.

When I open the same Live Script, under the same OS, but on my 2013 MBA, the PDF is generated with a thousand JAVA errors, BUT the PDF is not broken. Adobe Acrobat will open the PDF.

So it would appear that there is some interaction between the new crop of MBPs and MATLAB that is a problem. My MBP is Model Name: MacBook Pro Model Identifier: MacBookPro14,3 Processor Name: Intel Core i7 Processor Speed: 3.1 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 8 MB Memory: 16 GB Display: 15.4-inch (2880 x 1800) Graphics: Radeon Pro 560 4 GB ...

My version of Java is current. I typically run with an external Thunderbolt display, but that is not the issue - I get the same result on the MBP if I run only the laptop screen.

For me, and I would guess anyone that is trying to use Live Scripts as a way to generate class-ready materials as PDF that this is a significant problem.

I would add - whether a good PDF is generated or not... seeing all those JAVA errors is disconcerting, and puzzling.

Best, ---jon---

Hi Jon,

Thanks for your post!

I've some follow-up questions:

1. Is the broken PDF of zero size?
2. Do you see the issue only with a certain Live Script or with any (even empty) Live Scripts?
3. Could you please post a few of those Java errors? The very first ones would be sufficient.
4. I guess, the broken PDF made on the MBP can't be opened even on the MPA. And vice-versa, the PDF made on the MPA opens fine on the MBP. Can you confirm that?

Thanks in advance for your reply.

Hello! I have exactly the same issue as Jon (a long message error and PDF empty). I run MATLAB 2017a in macOs highSierra (10.13.1). I updated my computer to this last version of macOS yesterday and whenever I click on "export to PDF" I get the following error:

I have to say that this error has not appeared before updating to highSierra (I have been working with live scripts for the past 2 months with the older version Sierra).

Hope this helps you to try and find the bug in the software. Best Regards Steffany

Martin,

THANKS! Increasing the Java heap size by 50% did correct the problem on the LiveScript I was working with. Since you indicate that this problem was on some machines with the most recent Sierra (which is High Sierra, 10.13.1, I thoought you might want to know more characteristics of my machine. (Below - if more would be useful let me know.)

I really appreciate the responsiveness of the MathWorks in times like this!

Answer 2

[Martin Knelleken]

George, Steffany

Thanks for your reply/post. For unknown reasons, you're running out of Java memory on certain machines with the most recent Sierra version. We've to figure out why this happens and how to handle this more nicely.

For now you can try to increase the Java Heap Memory in MATLAB. See https://www.mathworks.com/help/ matlab/matlab_external/java-heap-memory-preferences.html

I expect an increase of 50% would be sufficient.

I hope that helps.

Hi Martin. I am experiencing the same problem. I have tried increasing the Java Heap memory but my file continues to stay broken and not opening. It also does not want to print. Any other suggestions?
