Review comment:
Incorrect data is worse. Users can fix issues with schemas if there is
an error but silent data mismatch typically goes unnoticed.

> Key: BEAM-12925

> Project: Beam
> Issue Type: Bug
> Components: io-java-jdbc
> Affects Versions: 2.32.0
> Reporter: Chris Gray
> Priority: P2
> Time Spent: 1h 10m
> Remaining Estimate: 0h

> Numerical values that are SQL NULL in the database are converted to 0 when
> read by `readRows`. This appears to be caused by SchemaUtil.java not
> checking `ResultSet::wasNull` at line 253 in version 2.32.0.
