**To Reproduce**
Try to build jar from source code using 'mvn package'. Fails during tests stage. Source code of pulsar 2.8.2

**Desktop (please complete the following information):**
- OS: Windows

**Additional context**
I'm new to Maven so perhaps I'm missing something

Reproduce the failure on the Pulsar 2.8.2 source with `mvn package`, then start at FastThreadLocalStateCleanerTest.java:88 and the ThreadLocalStateCleaner initialization referenced in the stack trace. Check whether the test still fails during the test stage, and consider the issue resolved when the package build completes without this NoClassDefFoundError.
