When you create a class and add a field to it, the javadoc for the constructor 
from the class template gets added to the field as well. The generated class 
looks like the following:

class MyClass {
/** constructor javadoc from template */
String myField;
/** constructor javadoc from template */
MyClass(){}
...
}

Attached is a patch for o.n.m.j2ee.common.source.GenerationUtilsTest that 
demonstrates the problem.
