[422573] Issue in IndexManager.getIndexer()

The implementation class of the indexer is created only once instead of
every time when getIndexer() is called. This makes the code more robust
of eventual issues when loading the implementation class.

If there is a CoreException thrown, it is always logged in the error
log.
