>Description:
The compiler fails to catch the use of `this' in a 
constructor before calling the superclass constructor.
>How-To-Repeat:
The following patch corrects invalid 
code in java/io/OutputStreamWriter.java.
Revert this patch.  The compiler should issue an error.
Compiling it with javac produces:

./java/io/OutputStreamWriter.java:35: Can't reference this before the superclass constructor has been called.
    super((this.out = (out instanceof BufferedOutputStream
