### Motivation
Fixed race conditions in thread safety tests that were causing intermittent
IllegalReferenceCountException failures due to improper resource cleanup order
and unrealistic concurrent write patterns.
### Modifications
1. Enhanced Thread Safety Test Design
- Fixed concurrent write race condition: Changed
testConcurrentContainsMessageWithWrites from concurrent writes to sequential
writes with concurrent reads, matching real-world
usage patterns where addMessage is called sequentially
- Improved test structure: Single writer thread generates sequential
ledgerIds (1000, 1001, 1002...) while multiple reader threads concurrently call
containsMessage()
- Added proper error handling: Enhanced exception tracking and reporting
with detailed logging
2. Fixed Resource Cleanup Race Condition
- Resolved IllegalReferenceCountException: Fixed tearDown method to shutdown
ExecutorService before closing tracker, preventing threads from accessing
released Netty ByteBufs
- Improved cleanup order: Ensures all background threads are terminated
before releasing resources

<!--
After opening this PR, the build in apache/pulsar will fail and instructions
will
be provided for opening a PR in the PR author's forked repository.
apache/pulsar pull requests should be first tested in your own fork since
the
apache/pulsar CI based on GitHub Actions has constrained resources and quota.
GitHub Actions provides separate quota for pull requests that are executed
in
a forked repository.
The tests will be run in the forked repository until all PR review comments
have
been handled, the tests pass and the PR is approved by a reviewer.
