--------------------------------------
Summary: CacheService should implement Closable / Review the
livecycle of the CacheService/MemoryService/ByteBufferAllocator objects
Key: DIRECTMEMORY-82
URL: https://issues.apache.org/jira/browse/DIRECTMEMORY-82
Project: Apache DirectMemory
Issue Type: Bug
Components: core
Affects Versions: 0.6.0
Reporter: Jeff MAURY
I think the CacheService should implement Closable. Each CacheService instance
holds a reference to a Timer, which starts an underlying Thread to execute
TimerTasks. As there is no way to know when the CacheService is stopped, lots
of "zombies" threads will be present in the JVM each time a reference on the
CacheService is not kept anymore (start/stop of a Web application, open/close
of an HibernateSessionFactory).
Please note that the patch I submitted for DIRECTMEMORY-81 shows now that lots
of Timer-xx threads are not executing and generating traces as several
instances of CacheService are created during the tests.
In general, I think we should review the lifecycle of the
CacheService/MemoryService/ByteBufferAllocator objects as only
ByteBufferAllocator implements Closable but the close method is never called
