### What changes were proposed in this PR? Interval Join read each key with `asInstanceOf`, which unboxes a null INTEGER, LONG or DOUBLE to 0, so a row with a null key joined as if the key were 0. A null TIMESTAMP key threw a NullPointerException and failed the run. A tuple whose key is null now produces nothing and never enters the operator's cache, so the comparisons never read a null. This matches the other joins, where a null key matches nothing. ### Any related issues, documentation, discussions? Closes #9002 ### How was this PR tested? A new case in `IntervalOpExecSpec` feeds a null key on each side for INTEGER, LONG, DOUBLE and TIMESTAMP, and checks that it joins nothing and that a later row still joins. It fails on main. The existing Interval Join tests pass. ### Was this PR authored or co-authored using generative AI tooling?
