HasThread (Apache HBase 1.4.11 API)

java.lang.Object
- org.apache.hadoop.hbase.util.HasThread

All Implemented Interfaces:

Runnable

Direct Known Subclasses:

HRegionServer, Leases, LogRoller
```
@InterfaceAudience.Private
public abstract class HasThread
extends Object
implements Runnable
```
Abstract class which contains a Thread and delegates the common Thread methods to that instance. The purpose of this class is to workaround Sun JVM bug #6915621, in which something internal to the JDK uses Thread.currentThread() as a monitor lock. This can produce deadlocks like HBASE-4367, HBASE-4101, etc.
