Description

IOException is a checked exception, which makes it difficult to use with lambdas. We should consider using UncheckdIOException instead.

I'll add notes below with code that could be simplified if we did this:

1. The private constructor of LazyIndex could take a factory method instead of all parameters and IndexType (like the Scala code used to). This would avoid some repetition and some unsafe casts.
