question: private static InputStream nullInputStream ( ) throws NullPointerException { if ( currentTimeMillis ( ) > 0 ) { return null ; } throw new NullPointerException ( ) ; }
target:  The following two methods exist because in, out, and err must be initialized to null.  The compiler, however, cannot be permitted to inline access to them, since they are later set to more sensible values by initializeSystemClass().
