I wrote a simple test to reproduce a very similar stack trace to the above
issue, where only some line numbers differences.
Any ideas as to why the following happens? Any help would be very
appreciated.
* The test case:
> @Test
> public void documentCommitAndRollbackTest() throws Exception {
>
> // Fix: SolrException: Error opening new searcher
>
> server.rollback();
> server.commit();
> }
* The similar stack trace (Which is repeated twice):
