ClassCastException during indexing

We're getting the following stack dump during indexing in our test Jira instance (v5.2, build 812). I've looked around and found similar issues/fixes, but they don't seem to apply in our case. Does anyone have any pointers? Thanks

Can you just try the following steps which clear up all the cache and rebuild all the indexing and bundled plugin files to see whether the problem is still reproducible or not:

  1. ShutdownJIRAinstance
  2. Delete the contents of<tt>JIRA Installation Directory\work</tt>directory
  3. Delete contents of the<tt>JIRA Home Directory\caches\indexes\changes</tt>directory
  4. Delete contents of the<tt>JIRA Home Directory\caches\indexes\comments</tt>directory
  5. Delete contents of the<tt>JIRA Home Directory\caches\indexes\entities</tt>directory
  6. Delete contents of the<tt>JIRA Home Directory\caches\indexes\issues</tt>directory
  7. Remove the content of the following directory:
    • <JIRA Home Directory>/plugins/.bundled-plugins
    • <JIRA Home Directory>/plugins/.osgi-plugins
  8. RestartJIRAinstance.
  9. Perform re-indexing.

Hope it helps!

I did what you suggested, and it still fails. However, the stack dump is different from before:

java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to java.lang.String
