I started adding error checks in RelBuilder, specifically adding NULL checks when looking up tables.
There are some options for exception reporting and I wanted to get a feel for preferred approach. I saw that there is already an InvalidRelException, which seemed pretty appropriate, but it is a checked exception, so means method signatures have to be changed. This seemed too disruptive, We could make this an unchecked exception? Otherwise is there some generic exception class I should use, or maybe just use IllegalArgumentException / IllegalStateException / RuntimeException ?
