Bad entity changes after field is added

If a entity (or any .java) is modified by Spring Roo some erroneous changes is made:

• Bad asterisk imports: "import java.utils.*;" becomes "import java.*;"
• Lose of Array fields: "String[] strings;" becomes "String strings;"
• Lose of Array constructor parameters: "Vet(String[] strings)" becomes "Vet(String strings)"

To test it:

1. create a new project using clinic.roo script.
2. replace Vet.java with attached Vet.java.changed file
3. Use Roo field command to add a field to entity:

   field string --fieldName foo --class ~.domain.Vet
   

4. When process finish Vet.java looks like Vet.java.error
