Hi @andreas1, Thanks for the additional information. To confirm, the image placeholder is pointing to an internal URL and still showing “Blocked URL”? You’re correct, in that case the image shouldn’t be blocked. Are you seeing any errors in the logs that you’d be able to share when you attempt to export to the page to a PDF? Any more information you could provide to help us reproduce this issue would help and we’ll keep an eye on the issue as requested. Thanks ---

Unable to reproduce this one on our end and nothing notable has changed with respect to this functionality in `m132`. This could potentially occur if there is a plugin bundling its own copy of `commons-lang3`. ---

@Kusal could you add `java.util.ImmutableCollections$ListN#isEmpty()` the global allowlist? This could probably be the case for several / all of the methods for ImmutableCollections. ---

Hi @Kusal , could you assist on this issues for us seem like the dom4j is in the list of grey api removal for third party library, we have no choice now, we did add the dom4j dependency as a compile scope and after that we did encounter castException like below when the plugin app execute **DocumentHelper.parseText(descriptorXml).getRootElement();** Is this is due to the DocumentFactory is implement as a singleton class and system bundle did’t expose this? ```auto Caused by: java.lang.ClassCastException: class org.dom4j.DocumentFactory cannot be cast to class org.dom4j.DocumentFactory (org.dom4j.DocumentFactory is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @33dc9660; org.dom4j.DocumentFactory is in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @6b7e1d49) at org.dom4j.DocumentFactory.getInstance(DocumentFactory.java:92) at org.dom4j.io.SAXReader.getDocumentFactory(SAXReader.java:667) at org.dom4j.io.SAXReader.createContentHandler(SAXReader.java:948) at org.dom4j.io.SAXReader.read(SAXReader.java:478) ``` ---

We’re getting ```auto java.lang.NoSuchMethodError: com.atlassian.confluence.status.service.SystemInformationService ``` However, I can’t find info about it being deprecated or how to replace it.

@metin, > `java.lang.NoSuchMethodError` That’s not due to Velocity allowlist, but rather that method `getGetStartedLink` does not exist in your `GlobalSettingsAction`. Indeed, the name _getGetStartedLink_ sounds odd; surely it should be _getStartedLink_, without the 2nd _get_, yes? Check your code; I suspect a bug on your end there. ---

In addition to the last post, it’d be nice to know: - Are there any other beta versions coming before GA? - Are we having a RC version with all the changes so that we can test a version with all major changes included prior to GA? - Is there a date set for GA? And a comment: ideally we should be given some time between RC and GA. Thank you. ---

Another issue we have is that we need to access `` attributes from `WebPanel`, but I don’t see a way to do this from the current API Use case is we’re migrating everything to XML registration, but in ScriptRunner we need to be able to pass a user script as an XML attribute, that the web panel can then execute/render. ---

`com.atlassian.plugin.web.model.WebPanel` doesn’t have `getParams()` though, it’s this specific interface that is problematic Elsewhere we have access via the method you note, or in a condition we can grab the params during `init` If we go via XML we’re stuck with what the `WebPanel` interface provides ---

Thanks a lot for your reply! > Indeed, the name _getGetStartedLink_ sounds odd; surely it should be _getStartedLink_ , without the 2nd _get_ , yes? It does sound odd, but the method name is indeed _getGetStartedLink_, because it’s supposed to get the url that the “Get Started” button links to. In the meantime, we’ve found out that our method uses `com.atlassian.confluence.core.ConfluenceActionSupport.getSystemInformationService()` which has been deprecated: > **Deprecated, for removal: This API element is subject to removal in a future version.** _since 8.5.5, use the_ `systemInformationService` _protected field directly when extending this class._ However, the `systemInformationService` protected field doesn’t exist in 7.x, and perhaps even pre 8.5.5 so we need to implement some kind of internal abstraction layer unless there is something available in the confluence-compat-lib which I haven’t checked yet. ---

We’re running into the same problem. Looks like it is impossible to use the web panel module type for 3rd party apps on Confluence 9.0.0-beta2. @mkemp I have not tried to reproduce with a minimal code example, but it should be as trivial as: 1. Create an app that can only use the public API (not `com.atlassian` namespace in plugin key, or whatever your secret is 🙂 ) 2. Add a webpanel module where the class implements the new `com.atlassian.plugin.web.api.model.WebPanel` interface (instead of the classic `com.atlassian.plugin.web.model.WebPanel`) 3. Try to install in beta2 and open a page where the webpanel is loaded @ggautam This needs to be fixed as soon as possible. Please do not release 9.0.0 with this bug. It breaks most of our apps. ---

I have a test project made with the `atlas-create-confluence-plugin` to help me with working out some of the fragment changes. If you check out the main branch and follow the readme it should reproduce the ClassCastException we are getting.
