Addresses #38925 (preparatory PR1a of 2).
## What changes
Raises the Java floor for IcebergIO and its dependent modules from **11 to
17**, in preparation for the upcoming Iceberg **1.11.0** upgrade (PR1b).
Iceberg 1.11.0 is published as Java 17 bytecode and drops Java 11, so the floor
has to move first. Splitting the floor raise into its own self-contained,
CI-green PR keeps the dependency bump (PR1b) minimal and lets CI validate the
Java 17 floor independently.
**`requireJavaVersion` 11 → 17** (Gradle's JVM-version variant resolution
will not let a Java 11 module depend on a Java 17 one, so these must move
together):
- `sdks/java/io/iceberg/build.gradle`
- `sdks/java/extensions/sql/iceberg/build.gradle` (depends on the IcebergIO
module)
- `examples/java/iceberg/build.gradle` (depends on the IcebergIO module)
**CI workflows** — the five `IO_Iceberg_*` GitHub Actions workflows now set
`java-version: 17` (they otherwise default to 11 via
`setup-environment-action`), matching the Delta and Debezium IO workflows:
- `.github/workflows/IO_Iceberg_Unit_Tests.yml`
- `.github/workflows/IO_Iceberg_Integration_Tests.yml`
- `.github/workflows/IO_Iceberg_Integration_Tests_Dataflow.yml`
- `.github/workflows/IO_Iceberg_Managed_Integration_Tests_Dataflow.yml`
- `.github/workflows/IO_Iceberg_Performance_Tests.yml`
## What does NOT change
- **No dependency bump here.** `iceberg_version` stays at 1.10.0; the bump
to 1.11.0 is PR1b (stacked on this PR).
- The Java IO expansion service (`sdks/java/io/expansion-service`) is
already Java 17 on master (#38974), so it needs no change.
- No public API change. `IcebergIO` is internal, exposed only via
`Managed.read(ICEBERG)` / `Managed.write(ICEBERG)`.
## Breaking change
Pipelines using `Managed.read(ICEBERG)` / `Managed.write(ICEBERG)`, and Beam
SQL's IcebergIO extension, now require a Java 17+ JVM. (The cross-language
expansion service already required Java 17 as of #38974.) Documented in
`CHANGES.md`.
## Verification
- `:sdks:java:io:iceberg:compileJava` and the dependent modules compile on
JDK 17.
- The five updated `IO_Iceberg_*` workflows run on Java 17.
