----------------------------------
Resolution: Fixed
> java.net.BindException: Address already in use in
> PartitionedRegionAttributesMutatorTest during concurrent execution
> --------------------------------------------------------------------------------------------------------------------

> Key: GEODE-10499
> URL: https://issues.apache.org/jira/browse/GEODE-10499
> Project: Geode
> Issue Type: Bug
> Reporter: Jinwoo Hwang
> Assignee: Jinwoo Hwang
> Priority: Major
>
> h2. Problem
> The {{PartitionedRegionAttributesMutatorTest}} is experiencing
> java.net.BindException: Address already in use (Bind failed) 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. Error Details
>
>
> java.net.BindException: Address already in use (Bind failed)
> at java.net.PlainSocketImpl.socketBind(Native Method)
> at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:387)
> at java.net.ServerSocket.bind(ServerSocket.java:375)
>
>
> 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. 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
