Problem

beam-sdks-java-harness bundled ~70 unrelocated org.apache.datasketches.memory.* classes frozen at v2.0.0 with no shade relocation. These conflict with datasketches-memory:3.0.2 pulled in
transitively via datasketches-java:3.0.0 in consumer MPs, causing linkage checker "missing method" errors.

Root cause: BaseWritableMemoryImpl in v2.0.0 extends BaseStateImpl (no AutoCloseable), but in v3.0.2 it extends ResourceImpl implements Resource (adds close()). Both versions share the same
FQCNs, causing binary incompatibility.

Fix

Add a shade relocation rule in sdks/java/harness/build.gradle to relocate org.apache.datasketches to org.apache.beam.repackaged.harness.org.apache.datasketches, following the same pattern already
used in sdks/java/core for commons-compress, commons-lang3, and antlr.

Verification

Before fix — ~70 unrelocated classes visible:
jar tf beam-sdks-java-harness-2.45.54-SNAPSHOT.jar | grep '^org/apache/datasketches/memory/'
returns ~70 classes

After fix — no unrelocated classes, all relocated to shaded path:
jar tf beam-sdks-java-harness-2.45.55-SNAPSHOT.jar | grep '^org/apache/datasketches/memory/'
returns nothing

jar tf beam-sdks-java-harness-2.45.55-SNAPSHOT.jar | grep 'datasketches'
returns org/apache/beam/repackaged/harness/org/apache/datasketches/...

Changes

• sdks/java/harness/build.gradle: add relocation rule for org.apache.datasketches
• buildSrc/.../BeamModulePlugin.groovy: bump version to 2.45.55
• gradle.properties: bump version to 2.45.55
