Hi,

I’m attaching the document now. I will have to obtain the environment details later in the day. All I know at the moment that it is running on a Red Hat Enterprise Linux.

Thank you!

@braintribe,

I have worked with source files and sample code shared by you and have been able to observe the issue. A ticket with ID SLIDESJAVA-37820 has been created in our issue tracking system to further investigate issue in detail. This thread has been linked with issue so that you may be automatically notified once issue will be fixed.

Hi,
Thank you very much. I’m very happy that you could reproduce the problem as we couldn’t in our environment.
Thanks!

@braintribe,

I like to inform that we have investigated this exception and it is related to the bug in Openjdk, because a similar exception is thrown on RHEL Server 6.9 with OpenJDK, but everything works fine with Oracle JDK on the same server. In this case, to fix this exception, we suggest using Oracle JDK instead of Openjdk. If you want to fix this exception for Openjdk, you can use "NPE in sun.awt.FontConfiguration.getVersion(…) " as a search phase and check which fix will help you.

Hi,

Thank you for your response. Unfortunately, I am not able to find any search result that would help me understanding / fixing the problem.
We also tried to uninstall all fonts but did not get the exception above (it was a different one, which was alright).
Do you have any more information on how to deal with this problem?
It would also be cool to be able to reproduce the problem locally? How did you manage to reproduce this?

Thank you for your help

@braintribe,

As we have shared earlier we have investigated on our end and have reached the conclusion that this is a bug in Openjdk, because a similar exception is thrown on RHEL Server 6.9 with OpenJDK, but everything works fine with Oracle JDK on the same server. In this case, to fix this exception, we suggest you to please use Oracle JDK instead of Openjdk. If you are still able to reproduce the issue using Oracle JDK, please feel free to share with us.

Hi,
Thank you for your reply.
Unfortunately, the trace

Root cause: java.lang.NoClassDefFoundError: Could not initialize class com.aspose.slides.internal.ey.this
at com.aspose.slides.internal.np.this.do(Unknown Source)

is not super-helpful in finding the actual cause of the problem and how to fix it when I’m stuck with OpenJDK. The code obfuscation I don’t mind, but the exception is still lacking important information, like the root cause. What classes does “com.aspose.slides.internal.ey.this” reference?

Please, don’t just tell me I should use OracleJDK. This is not good advise as I cannot decide what the customer is using or not. OpenJDK is also widely used, so it would be an interesting choice not to support it.

Your message,

was a good start. It indicates that you have a clue on what is going on. Could you please share your wisdom?

Thank you

@braintribe,

We have observed the stack trace and this exception occurs when Aspose.Slides tries to initialize fonts and java.awt.Container object.

Unfortunately, we cannot reproduce an exception with the same stacktrace, but we did manage to reproduce an exception which is very close to the your exception. In order to fix this exception we used the following commands:

yum install fontconfig
yum install dejavu-sans-fonts

Can you please try the specified commands and share feedback.

The issues you have found earlier (filed as SLIDESJAVA-37820) have been fixed in this update.
