war plugin invokes java:compile twice

[Sri Sankaran]

Using: Maven 1.0 rc2
 
Problem: Invoking the "maven war" results in java:compile being executed twice.
 
Tracing the logic of the goal "war" in the war plugin, you will find a call to 
"war:init".  In "war:init" are the following lines:
 
    <j:if test="${sourcesPresent == 'true'}">
      <caller:call goalInterface="compile-java"/>
      <attainGoal name="test:test"/>
    </j:if>

The caller plug-in invokes java:compile as instructed.  That is the first invocation 
of this goal.
 
The call to "test:test" can then be traced to have "java:compile" as a prerequisite.  
That is the second invocation.
 
Any circumstance where this is necessary?
