Review Comment:
Rather than using two static methods, you can use `DynConstructors` instead
to make this one expression and reduce error handling code:
```java
private static final DynConstructors.Ctor<SeekableInputStream> h2streamCtor =
DynConstructors.Builder(SeekableInputStream.class)
.impl("org.apache.parquet.hadoop.util.H2SeekableInputStream",
FSDataInputStream.class)
.orNull()
.build()
...
if (h2streamCtor != null) {
return h2streamCtor.newInstance(stream);
}
```
