System-Plugins won't activate, showing "license may be invalid" message

We are evaluating Confluence 4.2.13 right now. Yesterday our test-server was restarted -- that was not planned and not our decision. After the reboot Confluence started, but a few system-plugins refused to start. Now if we try to activate them manually, a message appears, saying The plugin cannot be activated. Your license may be invalid...

This problem concerns the activation of these plugins:

- Applinks Product Plugin

- jira-connector

- JIRA Macros

- ...and maybe a few others

Background information: We were trying to evaluate Confluence with a JIRA-integration. We established a sync between the user directories and we added the application link successfully.

Hi Giuliano,

thank you for your advice. I also contacted the Atlassian-Support. They gave me the same advice first, but it didn't work.

Their second advice though was helpfull and solved our problem - we raised the allocated memory. So the problem was caused by limited memory causing the initialization of plugins to fail after 30 seconds default timeout.

Best regards

Could you please try to remove everything under the following directories:

The _<confluence-home>/bundled-plugins_ folder
The _<confluence-home>/plugin-cache_ folder
The _<confluence-home>/plugins-osgi-cache_ folder
The _<confluence-home>/plugins-temp_ folder
The _<confluence-home>/bundled-plugins_language_ folder

This approach will remove all bundled plugins from your instance, they will be generated again once you restart Confluence.

Hope it helps!
