TODO

* ExtIntrosRefs.jrag
  - produce constructor REFs für super() and this() 
 
  - If the target is a constructor in a compilation unit reconstructed from 
    byte code, then the name of the cunstructor is <init>.  If the compilation
    unit comes from a source file, then normal constructor name is displayed.  TODO:
    make it consistent <init> or normal name.

* Report the problem with hostType() method in TypeParameters of GenericTypeDecl
  (see FujiCompiler/src/TypeAnalysisGenericsPatch.jrag)

* Output correct error messages on parser errors. See test ReportParseError2 (FAILED)

* Create a test case that demonstrates the JastAddJ bug
http://bugs.jastadd.org/cgi-bin/bugzilla/show_bug.cgi?id=41

* FieldMethodCompostion: create a testcase for refinement of methods and 
fields with changing modifiers.
