- When the code pasted below is executed, a MissingFormatArgumentException is raised (Format specifier 's').
- If setAction(..) is not called, no exception is thrown.
- Fixing the format call in ConcurrentUpdateSolrServer:164 might resolve the issue.
- The issue is present in trunk.
- I don't have the resources available to submit a proper patch at the moment, but might do so in the future. Meanwhile I'm posting this bug to let you know.
