The current implementation of selectSparkVersion() was broken when sparkVersion is supplied. The code was requiring an exact match instead of using contains(), which never matched real Databricks Runtime version names like "12.2 LTS (includes Apache Spark 3.3.2, Scala 2.12)". This change aligns the Java SDK with the Go and Python SDK implementations, which both use contains()/in operations for sparkVersion matching. Fixes the issue described in PR #229. Added comprehensive unit tests covering: - Successful spark version matching with realistic API response data - Multiple matches with latest=true/false behavior - Integration with other selector parameters (ML, etc.) - Error cases for non-existent versions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

What changes are proposed in this pull request?
This PR fixes a bug in the
selectSparkVersion()method inClustersExt.javawhere spark version matching doesn't work with real Databricks Runtime version names.The current
equals()implementation fails because real Databricks Runtime version names contain additional information. For example, the actual version name is"13.3 LTS (includes Apache Spark 3.4.1, Scala 2.12)", not just"Apache Spark 3.4.1". Both the Go SDK (strings.Contains()) and Python SDK (inoperator) use substring matching for this functionality.Originally reported in PR #229 with real API response data.
How is this tested?
Added a focused unit test
sparkVersionWithSparkVersionParameter()that demonstrates the fix works with realistic API response data. The test uses a version name in the actual format returned by the Databricks API:"13.3 LTS (includes Apache Spark 3.4.1, Scala 2.12)".Fixes #229
