Cherry-pick of #8325 to ensure that downstream users can depend on Iceberg 1.11.0 succesfully, but with two important changes:

  • The actual bump to Iceberg 1.11.0 is not done. This is not currently possible given rc/v42.x has Java 11 source compatibility; Iceberg was bumped from 1.10.1 to 1.10.2.
  • The update to io.deephaven.iceberg.internal.Explore.partitionStats is not possible, given the APIs used are new in Iceberg 1.11.0. This means that downstream users who are on Iceberg 1.11.0 will get ClassNotFound, or similar, exceptions when trying to call this method. This is acceptable given that these are internal / utility methods.

* The actual bump to Iceberg 1.11.0 is _not_ done. This is not currently possible given rc/v42.x has Java 11 source compatibility.
* The update to `io.deephaven.iceberg.internal.Explore.partitionStats` is not possible, given the APIs used are new in Iceberg 1.11.0. This means that downstream users who are on Iceberg 1.11.0 will get ClassNotFound, or similar, exceptions when trying to call this method.
