Cannot Create a Space & log shows, "Package Scanner found duplicates for package 'javax.annotation'"

[Shane Parkinson]

After upgrading to Confluence 6.13, the log file contains the following warning:

[org.twdata.pkgscanner.ExportPackageListBuilder] logDuplicateWarning Package Scanner found duplicates for package 'javax.annotation' with different versions. Files: javax.annotation-api-1.3.2.jar and jsr305-3.0.1.jar
  '/opt/atlassian/confluence/confluence/WEB-INF/lib/javax.annotation-api-1.3.2.jar'
  '/opt/atlassian/confluence/confluence/WEB-INF/lib/jsr305-3.0.1.jar'

The next message in the log is:

WARN [FelixStartLevel] [extender.internal.support.ExtenderConfiguration] addDefaultDependencyFactories Gemini Blueprint extensions bundle not present, annotation processing disabled.

I'm not sure if this is the cause of another post upgrade problem where I can no longer create a space in Confluence. The dialogue that appears contains the error message:

"An unknown server error has occurred." 

I'm trying to work out if they are related.

When the dialogue appears, with the above error, the only entry that appears in the log file is the hibernate warning below

2019-01-08 11:52:22,256 WARN [http-nio-8090-exec-4] [confluence.impl.hibernate.ConfluenceHibernateTransactionManager] doRollback Performing rollback. Transactions:

Has anyone seen this error and if so what needs to be done to fix it?

Shane,

These are warning messages, and they don't appear to be related to your issue creating a space.

Can you confirm the name of the log file you're looking into? When you receive an error about creating a space in Confluence, an error is logged in the Confluence server application logs.

If you need help finding the related error message in the logs, I could go ahead and help you to raise a support ticket so we can have a look at your Support Zip.

Regards,

Shannon

I fixed the Space Issues by using the fix described in the following forum post, https://community.atlassian.com/t5/Confluence-questions/Unknown-server-error-when-trying-to-create-a-space/qaq-p/903634, which fixed the issue with the space Dialogue Error when trying to create a new space.

The "Create New Space" dialogue problem was introduced after upgrading from 6.11 to 6.13.  

The first error, "logduplicateWarning", shown below, is still being logged into the Atlassian-confluence.log file during startup.

I would have thought this error would have been very obvious during testing as the Confluence installation directory is completely replaced during the automated upgrade option w so I'm rather confused as to why this is appearing when you run the installer.

I've just restarted the server and on this restart, it doesn't display these warning messages,

logDuplicateWarning Package Scanner found duplicates for package

Shane,

Glad to hear you tracked down the issue with creating a space and were able to resolve it.

As for the message about duplicates, I know this kind of thing was a bug in the past, for example:

• CONFSERVER-54327 Package Scanner found duplicates for package 'javax.transaction.xa'

From your last reply, you are no longer seeing the message after restart?

Shannon
