Hi @tahir.manzoor thanks for the issue creation.
Do you have a time frame for the fix? We want to update to the latest library version because it fixes a different issue which you’ve resolved but this new problem is blocking us from doing so.
Any ETA would be greatly appreciated so that we can factor this in to our own release schedule.
Cheers, ThomasR

Thanks for reporting this issue thomask15t. I am facing the same issue and would also be interested in a fix date
+1 we’re also blocked from upgrading until there’s a fix for this (we’re using it in a Spring app rather than OSGI, but it’s the same fundamental issue).
@arronhardenels @chrisbeecham2 @TR-K15t @thomask15t The issue is already resolved. The fix will be included into the next version of Aspose.Words for Java, which we are going to release in approximately a week.
The issues you have found earlier (filed as WORDSJAVA-2584) have been fixed in this Aspose.Words for .NET 21.6 update and this Aspose.Words for Java 21.6 update.
Hi,
unfortunately this is still not fixed for us. As my colleague @thomask15t pointed out earlier, the spring-boot scenario was just one example - the fastest way to provide you with a standalone application.
Our real use case is a Confluence server plugin. Confluence uses Apache Felix as OSGi container and we believe that the classloader for Confluence plugins handles nested JARs a little bit different from the way the spring-boot classloader does wrt. to the URL representing the resources in nested JARs.
With the latest version we’re running into this error:
java.lang.ExceptionInInitializerError

How can we move forward here?
This issue prevents us from upgrading to future versions so we need a solution eventually.
Thanks,
Jens
We logged separate issue as WORDSJAVA-2587 to test different use cases of Jar signature check. We will inform you once this issue is resolved.
Please share this detail with complete steps to test your use case. We will investigate the issue and log it in our issue tracking system.
Thanks for your response. We’'ll collect all necessary details and post them here.
One question though: Would a Confluence plugin demonstrating this be helpful here? I’m asking because it will be some effort for us to create this and it would be only useful if one of your developers would actually run a Confluence instance to install this plugin into. Let us know if you still want such a plugin.
Could you please try the latest version of Aspose.Words for Java 21.7 at your end and let us know how it goes on your side?
Hi @tahir.manzoor.
I’m still running into an error with 21.7. Here’s the stacktrace and some details I retrieved by attaching a debugger from an IDE to the Confluence process.
Stacktrace:

The origin of the IllegalStateException is in com.aspose.words.zzWh2#zzWCe. Here are some details from its execution:
var1 = this.getClass(); --> class com.aspose.words.zzWh2
var1.getClassLoader(); --> com.k15t.scroll.word-server [348]
var1.getClassLoader().getClass(); --> org.apache.felix.framework.BundleWiringImpl
var1.getClassLoader().getResource("com/aspose/words/resources/3dBubble.jpg") --> bundle://348.0:28/com/aspose/words/resources/3dBubble.jpg
var1.getProtectionDomain().getCodeSource().getLocation().toString(); --> file:/Users/jens/k15t/confluence-7.12/home/plugins-cache/1626677415041scroll-word-server-5.2.6-SNAPSHOT.jar
var1.getProtectionDomain().getCodeSource().getCertificates() --> null
That last line explains why the check fails.
Please note how the codesource refers to our jar, not the aspose-words.jar which is bundled in META-INF/libs. Result of unzip -l scroll-word-server-5.2.6-SNAPSHOT.jar | grep aspose:
15957335 07-19-2021 08:29 META-INF/lib/aspose-words-21.7-jdk17.jar
Please let me know if you need further information.
Thanks,
Jens
