>                 URL: https://issues.apache.org/jira/browse/LUCENE-1552
>             Project: Lucene - Java
>          Issue Type: Bug
>    Affects Versions: 2.4
>         Environment: Java
>            Reporter: Scott Garland

> After this bit of code in addIndexes(IndexReader[] readers)
>  try {
>         flush(true, false, true);
>         optimize();					  // start with zero or 1 seg
>         success = true;
>       } finally {
>         // Take care to release the write lock if we hit an
>         // exception before starting the transaction
>         if (!success)
>           releaseWrite();
>       }
> The success flag should be reset to "false" because it's used again in another try/catch/finally block.  
> TestIndexWriter.testAddIndexOnDiskFull() sometimes will hit this bug; but it's infrequent.
