>            Reporter: Dennis Balkir

> ExecutionPool.java:122, EQ_COMPARETO_USE_OBJECT_EQUALS
> Eq: org.apache.ofbiz.base.concurrent.ExecutionPool$Pulse defines compareTo(Object) and
uses Object.equals()
> This class defines a compareTo(...) method but inherits its equals() method from java.lang.Object.
Generally, the value of compareTo should return zero if and only if equals returns true. If
this is violated, weird and unpredictable failures will occur in classes such as PriorityQueue.
In Java 5 the PriorityQueue.remove method uses the compareTo method, while in Java 6 it uses
the equals method.
> From the JavaDoc for the compareTo method in the Comparable interface:
> It is strongly recommended, but not strictly required that {{(a.compareTo(b)==0) == (a.equals(b))}}.
Generally speaking, any class that implements the Comparable interface and violates this condition
should clearly indicate this fact. The recommended language is "Note: this class has a natural
ordering that is inconsistent with equals."
