> h2. Problem
> The {{PartitionedRegionAttributesMutatorTest}} is experiencing [java.net.BindException: Address already in use (Bind failed)|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html] errors when running in concurrent execution environments. This issue occurs when multiple test instances attempt to bind to the same port simultaneously, leading to port conflicts and test failures.
> The error indicates that the current port allocation mechanism is not providing sufficient isolation between concurrent test executions, particularly in CI/CD environments where multiple test suites run in parallel.
> h2. Steps to Reproduce
>  # Run multiple instances of PartitionedRegionAttributesMutatorTest concurrently:
>  
>  
> ./gradlew test --tests "*PartitionedRegionAttributesMutatorTest*" --parallel
>

>  
>  # Or run the full test suite with parallel execution enabled
>  # Observe BindException failures related to port conflicts

> h2. Root Cause
> The current port allocation strategy does not provide adequate isolation for concurrent test execution, leading to multiple tests attempting to bind to the same ports simultaneously.
> h2. Proposed Solution
> Integrate the enhanced [TestSafePortSupplier|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html] class (already implemented in geode-junit) which provides:
>  * Process-specific port ranges to avoid conflicts
>  * Thread-safe port allocation with retry logic
>  * Cross-process coordination via port registry
>  * Better port availability validation
> h2. Technical Details
> The [TestSafePortSupplier|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html] addresses this issue by:
>  * Allocating unique port ranges per process (1000 ports each)
>  * Using atomic counters for thread-safe port selection
>  * Implementing retry logic with exponential backoff
>  * Maintaining a registry of used ports across processes
> h2. Acceptance Criteria
>  *  PartitionedRegionAttributesMutatorTest passes consistently in concurrent environments
>  *  No BindException errors related to port conflicts
>  *  Tests can run in parallel without port collisions
>  *  Backward compatibility maintained with existing test infrastructure
>  *  Performance impact is minimal (< 5% test execution time increase)
> h2. Environment
>  * {*}Project{*}: Apache Geode
>  * {*}Test Class{*}: PartitionedRegionAttributesMutatorTest
>  * {*}Issue Type{*}: Concurrency/Port Conflict
>  * {*}OS{*}: All supported platforms (Linux, macOS, Windows)
>  * {*}JVM{*}: All supported versions
> h2. Priority
> *High* - Blocking parallel test execution and CI/CD pipeline reliability
