## Description In portable Beam pipelines and Beam YAML running inside the Java SDK harness container (`FnHarness`), `StringCompiler` failed to resolve `org.apache.beam.sdk.values.Row` when dynamically compiling schema transforms/UDFs (such as `JavaFilterTransformProvider` and `JavaRowUdf`). This failure occurs because `FnHarness` launches with a `pathing.jar` containing manifest `Class-Path` entries. On modern JDKs (JDK 11+), `AppClassLoader` does not extend `URLClassLoader`, which previously caused manifest parsing to be skipped. Furthermore, manifest paths were not resolved from `java.class.path` or unescaped from `file:` URI schemes. ## Changes Made - Expanded `StringCompiler.buildClasspath` to inspect `Class-Path` manifest attributes of JAR files present on `java.class.path`. - Added support for space-separated tokens, `file:` URI schemes, and relative paths within manifests. - Added direct resolution of `Row.class` and `StringCompiler.class` locations via `ProtectionDomain.getCodeSource()` and `ClassLoader.getResource()`. - Added unit and regression tests in `StringCompilerTest` to verify manifest resolution and successful `Row` compilation. ## Testing - `./gradlew :sdks:java:core:test --tests "org.apache.beam.sdk.schemas.transforms.providers.StringCompilerTest"` (6/6 passed) - `./gradlew :sdks:java:core:test --tests "org.apache.beam.sdk.schemas.transforms.providers.*"` (12/12 passed) - `./gradlew :sdks:java:core:spotlessCheck` (BUILD SUCCESSFUL) ## Related Issue Closes #41079 -- This is an automated message from the Apache Git Service.
