> The root element I am indexing LegacyCarPlant has a reference to LegacyCar, which in turn embeds a collection of LegacyTire.
> When I kick off the indexer, I always get a LazyInitializationException on the collections.
> (PS: See stack trace at the tail end)
> If I make them eager, then the issue goes away, but ideally, I don't want to fetch them eagerly. I'll much rather prefer they remain lazily fetched for obvious reasons.
> The alternative is to crawl through in a loop and index using fullTextSession.index(T), but that is really really slow as I have upwards of 3million records and still growing.
> I have read the forums and tried all the suggestions I have seen including trying to run it on a single thread like
> fullTextSession.createIndexer(LegacyCarPlant.class)
> .batchSizeToLoadObjects(30)
> .threadsForSubsequentFetching(1)
> .threadsToLoadObjects(1)
> to no avail.
> Also, I have tried with the snapshot of 3.4.0 and the same error exists.
> If I do make the root element LegacyPlant, then I don't get the error as well. In my situation though, I need to have LegacyCarPlant be the root.
> The test program is "legacy_index_run.groovy"
