ThreadLeakChecker (Infinispan Commons Test Dependencies 11.0.17.Final API)

java.lang.Object
- org.infinispan.commons.test.ThreadLeakChecker

```
public class ThreadLeakChecker
extends Object
```
Check for leaked threads in the test suite.
Every second record new threads and the tests that might have started them. After the last test, log the threads that are still running and the source tests.

Strategies for debugging test suite thread leaks:
- Use -Dinfinispan.test.parallel.threads=3 (or even less) to narrow down source tests
- Set a conditional breakpoint in Thread.start with the name of the leaked thread
- If the thread has the pattern of a particular component, set a conditional breakpoint in that component
