> If an undeclared constructor is called in a consequence, a very strange error message is produced:
>    - error text is "Failed to compileShared" ("Shared" is not used by the app)
>    - The message part meant ot identify the location of the error is misleanding, e.g.,
>       Near : {... p3.setName( "Paul" ); ....}
>      with the marker ("^") pointing to "Paul".
>   public static class Person {
>         private String name;
>         public Person(String name){
>             this.name = name;
>         }
>         public String getField1() {
>             return field1;
>         }
>         public void setName( String name ) {
>             this.name = name;
>         }
>         public String getName() {
>             return name;
>         }
>     }
>     @Test

>         String str = "";
>         str += "package org.simple ";
