Error creating bean with name at startup of Jira 7.9.2

[Michaël de Checchi]

Hello.

Since the last upgrade from Jira 6 to Jira 7.9.2 I encounter issues to make my report plugin work.

I was able to fix the first issue by updating the dependencies (see https://community.atlassian.com/t5/Jira-questions/ReaderCache-and-IssueIndexManager/qaq-p/587073#M283626).

But now I have the following error when running Jira locally 

[INFO] [talledLocalContainer] ___ FAILED PLUGIN REPORT _____________________
[INFO] [talledLocalContainer]
[INFO] [talledLocalContainer] 1 plugin failed to load during JIRA startup.
[INFO] [talledLocalContainer]
[INFO] [talledLocalContainer] 'org.jahia.modules.jira.reports.jira-report-plugin' - 'jira-report-plugin' failed to load.
[INFO] [talledLocalContainer] Error creating bean with name 'issueFactory': FactoryBean threw exception on object creation; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.sun.proxy.$Proxy2448

[INFO] [talledLocalContainer]
[INFO] [talledLocalContainer] It was loaded from C:\Sources\jira-report-plugin\target\jira\home\plugins\installed-plugins\jira-report-plugin-1.1.0-SNAPSHOT.jar

And this is the case for all the attributes of my report class.

Can somebody help me on that ? :-)

('ve created a ticket for that but not sure if it will be seen/taken https://jira.atlassian.com/browse/JSWCLOUD-17122)
