public abstract class HasThread
extends java.lang.Object
implements java.lang.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.
